Good morning, everyone. For the fifth consecutive quarter, we posted record results demonstrating our unique positioning and continued momentum. In the second quarter, adjusted EBITDA plus net deferrals and net finance contracts was up 7% compared to the second quarter of 2022 and up 48% compared to the second quarter of 2019. This is an especially notable achievement when you consider that we've sold $2.3 billion in real estate net of acquisitions since the beginning of 2019. Our ongoing transformation has significant momentum and the second quarter results continue to reinforce our confidence in executing the strategy we outlined at our Investor Day in May. During our Investor Day we highlighted Hyatt's transformation positioning the company as the preferred brand for high-end guests in each segment that we serve, while creating significant value for shareholders. Since the beginning of 2017, we've driven shareholder value by realizing proceeds of $3.8 billion from the sale of owned hotel real estate, net of acquisitions at a multiple greater than 16 times, acquired $3.7 billion of asset-light and fee-based platforms at a multiple of approximately 8x and returned over $2 billion to shareholders through common stock repurchases and dividends. We've experienced meaningful growth doubling our luxury rooms, tripling our resort rooms and quadrupling our lifestyle rooms. As a result, today we are more fee-based and asset-light with a much higher conversion of reported earnings to cash flow. We anticipate that substantial free cash flow from our increased asset-light earnings mix. In addition, the proceeds from asset dispositions will enable us to invest in growth, return capital to shareholders and maintain our investment-grade profile. Through the disciplined execution of our strategy we have outlined a path where we expect to achieve $750 million in free cash flow and an 80% asset-light earnings mix by 2025. Our asset-light fee-driven model combined with industry-leading net rooms growth demonstrates our earnings strength and durability. We also expect to significantly reduce our capital expenditures to a run rate of approximately $100 million by 2025. The journey to transform our earnings profile is well underway and we are confident in our ability to execute the strategy and achieve the long-term projections that we outlined at our Investor Day. The successful execution of our strategy has led to a significant growth of the World of Hyatt program, which added seven million new members in the past 12 months, an increase of 20%. And we continue to see strong enrollments at our ALG properties that have signed up over 650,000 new loyalty members since the launch in May of 2022. Additionally, Legacy Hyatt system-wide rolled of Hyatt room penetration increased 140 basis points in the first half of 2023 compared to the same period in 2022. To further deepen loyalty with our existing World of Hyatt members and attract new members, we announced several key initiatives this quarter. First, the announcement of Hyatt Studios our first Upper midscale brand in the Americas has been well received by our ownership community. Letters of interest for over 100 hotels have begun converting to signed contracts and we expect the first property to open in the second half of 2024. Second we completed the acquisition of Mr & Mrs Smith a global travel platform that enhances our luxury offerings and provides access to a collection of more than 1500 boutique and luxury properties across the globe with the concentration in Western Europe. We have seen the power of leveraging an effective distribution platform in a complementary segment with ALG vacations and we plan to enhance the value proposition for the owners of hotels represented on the Mr & Mrs Smith platform, while also expanding the choices for our members and guests. Third we successfully integrated Lindner Hotels in Europe and Dream Hotel Group into the World of Hyatt loyalty programs strengthening our lifestyle portfolio. The speed of integration of these two platforms enables us to deliver value quickly for our owners and guests. These strategic initiatives demonstrate our commitment to deliver unique experiences, expand our global presence and strengthen our role of Hyatt loyalty program. Moving to our latest business trends. I'm pleased to share the comparable system-wide RevPAR for the second quarter increased 15% compared to the second quarter of 2022 and 8% compared to the same period in 2019 for the same set of comparable properties. Average rates increased 5% compared to a very robust second quarter of 2022 and are 15% higher compared to the second quarter of 2019 for the same set of comparable hotels on a constant currency basis respectively. Additionally, occupancy contributed meaningfully to RevPAR growth in the second quarter increasing 660 basis points compared to the same period last year. The second quarter reached a post-pandemic record with absolute occupancy of 72%, which is below 2019 levels by 450 basis points. Average daily rates remain strong and we believe occupancy gains will continue to drive future growth. Turning to our customers. Leisure transient revenue growth sustained in the second quarter increasing 7% compared to the second quarter of last year. These results are particularly impressive considering the pent-up demand that drove very strong results in the second and third quarter of 2022 due to Omicron's impact. While the year-over-year growth has moderated compared with the first quarter of this year, overall results in the second quarter continue to be very strong as we anticipated. Compared to the second quarter of 2019, leisure transient revenue increased by 26% in the second quarter, a 200 basis point improvement from the growth that we realized in the first quarter of this year compared to the -- continue to prioritize travel. We're also pleased to see the recovery in business transient revenue continuing to gain momentum up 36% compared to the second quarter of 2022 and 86% recovered to the second quarter of 2019. Led by large corporate accounts in the Americas, the recovery accelerated during the quarter with May and June 90% recovered when compared to the same months in 2019. Group revenue in the quarter was up 14% compared to the second quarter -- 2019 even though room night demand was down 12%. From a geographic perspective, we continue to see recovery momentum in Asia Pacific and strong results in the rest of the world. Greater China RevPAR surpassed pre-pandemic levels for the first time up 6% in the second quarter. Markets traditionally dependent on international inbound travel integrator China like Shanghai and Shenzhen were below second quarter 2019 levels, but have shown meaningful improvement compared to the first quarter of this year. Outside of Greater China, performance in Europe was outstanding as RevPAR increased 23% compared to the second quarter of 2022 and was up 30% compared to the same period in 2019. Finally, RevPAR in the United States remains resilient, increasing 4% compared to the second quarter of 2022 and remains above 2019 levels. Turning to ALG. Comparable net package RevPAR increased -- 18% in the first half of 2023. This quarter marks the one-year anniversary of the introduction of the World of Hyatt at ALG Resorts in the Americas, and we are thrilled to see strong adoption by our world of Hyatt members. In the Americas, World of Hyatt members accounted for approximately 22% of room nights at ALG Resorts during the first half of the year. As we look to the rest of 2023, we expect net package RevPAR growth to moderate in the second half of the year, relative to the second quarter, as a result of lapping extremely strong results in the second half of 2022 due to the condensed leisure travel season last year. Gross package revenue for the second half of 2023 is pacing 8% ahead of 2022. Turning to Group Pace for the Americas full service managed properties. Group revenue was up 31% in the first half of 2023, and Pace for the second half of 2023 is up 8% compared to the same periods in 2022. We had an extremely strong quarter booking nearly $500 million in the Group business for all future periods, an increase of 36% to the second quarter of 2022 and this was the highest Group production quarter since the first quarter of 2019. We're seeing the booking window lengthening, with approximately two-thirds of group production booked for dates beyond 2023 setting us up for strong opportunities to yield rates into the future. For 2024, specifically, group pace is up 10% with average rates and room nights each up approximately 5% and I'm extremely excited about the future, as group room night demand continues to recover back to 2019 levels. The combination of group production trends and 2024 Group Pace, reinforces our confidence to achieve the illustrative RevPAR growth range that we provided during our Investor Day in May. In summary -- we're benefiting from the tailwinds from Greater China sustained demand for leisure travel, recovery of business transient travel and strong sustained demand for groups and events. We believe the combination of our commercial platforms and best-in-class hotel teams is driving higher loyalty preference, hotel profits and as a result, increasing owner preference. The growth in our footprint and pipeline is the direct outcome of owners preferring our brands. During the second quarter, we achieved an impressive 6.9% net rooms growth over the trailing 12-month period. Notably, conversion opportunities remained a significant contributor to our net rooms growth this quarter. We introduced the Impression by Secrets brand, to the inclusive collection this quarter, an ultra luxury brand that further solidifies our position, as the largest manager of luxury all-inclusive resorts in the world, including the newly opened Impression Isla Mujeres by Secrets in Mexico. For our Legacy Hyatt portfolio, we expanded our presence in key cities like London and Mexico City, while also adding luxury offerings with the openings of Andaz Nanjing Hexi in China and the Grand Hyatt La Manga Club Golf & Spa in Spain. Our pipeline reached a new record of 119,000 rooms representing a 5% increase year-over-year and up sequentially from the first quarter, with new signings outpacing new openings. The expansion of our pipeline and ability to convert existing hotels to our brand gives us confidence we will continue to realize outsized growth into the future. I want to provide an update on our real estate transactions. We continue to make progress on two assets that we currently have on the market for sale and we expect to be under contract for one asset and select a buyer for the other asset soon. We remain focused on realizing the most attractive valuations and securing durable long-term management or franchise agreements. And we continue to remain highly confident in our ability to achieve our $2 billion sell-down commitment by the end of 2024. Lastly, I'm pleased to report continued to remain progress on World of Care, which drives alignment across Hyatt and how we advance care for the planet people and responsible business to support thriving destinations around the world. We just published our 2022 World of Care report this week and our global teams are advancing care for the planet through continued actions towards our 2030 environmental goals that address carbon reduction, water conservation and responsible sourcing. Our hotel teams are bringing innovative solutions to meet these goals such as our 2022 Food Waste Reduction pilot program and adoption of 100% Renewable Electricity in US Hyatt-owned hotels. In connection with advancing care for people, we believe that our teams should reflect the diversity and experiences of the communities in which Hyatt operates hotels. And we continue to support that diversity in leadership positions across our workforce. We have also exceeded our 2025 goal for expansion of our spend with diverse suppliers and identified new opportunities to support businesses in underinvested communities through efforts like holding deposits at minority-owned banks and helping to expand suppliers businesses in several markets. The creativity and passion of our teams is powering our success in meeting our environmental and social sustainability goals and is one of the main reasons why, institutional investor recognized World of Care as a top three ESG program in 2023 in the mid-cap gaming and lodging category. In closing, I'm very pleased with another quarter of record results. I want to extend my gratitude to the entire Hyatt family for their dedication in executing our strategy and positioning Hyatt as the preferred brand for colleagues, guests, customers and owners. Our asset-light earnings mix is yielding strong free cash flow, and we remain confident in our ability to drive exceptional results for all our stakeholders. Joan, will now provide more details on our operating results. Joan, over to you.
