Anthony Capuano
President and Chief Executive Officer at Marriott International
Thanks, Jackie, and thank you all for joining us today. Our terrific second quarter results demonstrate the strength of global lodging demand and the success of our growth strategies. I've experienced a robust demand for lodging firsthand as I've been on the road a lot this year and have had the privilege of visiting every one of our regions. It has been wonderful to spend time with our team of hard working and dedicated associates at properties around the world and to see how quickly global travels has rebounded.
Second quarter worldwide RevPAR rose 13.5% versus the 2022 quarter, led by another quarter of meaningful recovery in Greater China. Less than two quarters after travel restrictions were lifted, RevPAR in Greater China has now surpassed 2019 levels, primarily due to the surge in domestic demand. Worldwide occupancy in the quarter reached 72%, 5 percentage points higher than the year ago quarter. With our unwavering focus on maximizing revenues, global ADR grew 6% year-over-year.
Global leisure demand and ADR remained robust. Second quarter leisure transient room nights and ADR each increased 5% year-over-year, yielding 10% revenue growth. In the US and Canada, leisure revenues rose 1% above last year's sensational second quarter. Demands in this market has been stabilizing on a year-over-year basis with travelers from the region increasingly taking vacations overseas now that pandemic-related travel restrictions are behind us. Leisure room nights from the US and Canadian travelers jumped 90% in Asia Pacific and over 20% in Europe compared to the same period last year.
The Group segment had another great quarter with revenues in the US and Canada growing 10% year-over-year, driven by both rate and occupancy. Group revenues are expected to remain strong going forward. At the end of June, group revenue for the back half of 2023 was pacing up 11% to last year.
Meeting planners are beginning to book further out, a trend we're also seeing with transient customers. Group revenue for full year 2024 was pacing up 14% year-over-year at the end of the quarter, an improvement from up 9% just three months prior. Recovery in business transient demand remained slow, but steady with demand from our top corporate accounts progressing modestly in the quarter. In the US and Canada, ADR again rose nicely compared to 2022, thanks to high single-digit special corporate rate increases. This led to business transient revenues rising 12% year-over-year.
Overall, cross-border travel demand also rose again in the quarter, primarily driven by an increase in international visitors to the Asia Pacific region. The percent of total room nights from cross-border guests is now roughly 1 percentage point below 2019 levels of approximately 20%. Prior to the pandemic, international visitors accounted for nearly one-quarter of room nights in Greater China. With the region's international airlift still only around 40% of 2019 capacity at the end of the second quarter, we believe there is still meaningful growth opportunity in and from Greater China.
We remain keenly focused on strengthening our powerful Marriott Bonvoy loyalty program, which has over 186 million members. To further build engagement, we continued to enrich the platform with an enhanced booking experience, more choices for customers and complementary products that drive more value and capture share of wallet, such as our co-branded credit cards and travel insurance. Our international credit cards had a record quarter driving global card acquisitions up 25% and global card spend up 10% versus the year ago quarter.
We are increasingly leveraging technology to enhance the guest experience, to drive profitability for our owners and to simplify processes for our associates. As we've mentioned previously, we are in the process of a major global transformation of our digital and core technology. We will be launching new reservations, loyalty and property management platforms over the next several years and look forward to the numerous capabilities these new systems will offer our key constituents.
As we focus on paths for growth, we are adding new offerings and experiences in segments where we believe there is strong consumer interest beyond our current brands. A great example is our recent announcement of an exclusive 20-year strategic license agreement with MGM Resorts International and the creation of MGM Collection with Marriott Bonvoy. The collection which will launch beginning in October, encompasses 17 resorts with 40,000 rooms. This deal will provide us with significant presence in Las Vegas, one of the most popular destinations in the country with fantastic properties like Bellagio, the MGM Grand and ARIA as well as additional distribution in five other key US cities. Beyond just hotels, our strategic agreement with MGM will also give our members access to more sports, music, culinary and entertainment experiences.
We also recently announced our plans of new affordable mid-scale extended stay offering in the US and Canada. Our deep experience and leading position in extended-stay lodging, coupled with the recent trends toward increased work flexibility and longer stay travel, make us very optimistic about our growth potential. While it is still early days, initial interest from the development community has been extraordinary. We are working on several hundred deals and hope to have our first deal signed by the end of this year.
In the Caribbean and Latin America, we're very excited about the recent addition of City Express to our brand lineup. These mid-scale properties have started to join our distribution channels, and we are thrilled with the noticeable uplift in conversion rates, ADR and bookings so far.
Our development team remains focused on driving conversions, especially multi-unit opportunities, and interest from owners remains robust. In the first half of this year, convergence accounted for 21% of our organic room additions, including MGM, conversions represented 63% of our organic signings through June. The MGM rooms entering our system beginning this fall will boost our rooms distribution in 2023 by 2.4%. With more than half the year behind us, we have refined our full year net rooms growth expectations to 6.4% to 6.7%. Driving valuable global growth is a top company priority, and we are very pleased with the strong rate at which we expect our industry-leading system to grow this year.
We look forward to sharing more about many key aspects of our business, including our broad global portfolio of over 30 brands, their exciting growth prospects all over the world, Marriott Bonvoy, the brand that brings it all together, our technology transformation and our multiyear financial model at our Investor Day on September 27.
Now I'll hand the call over to Leeny to discuss our second quarter financial results in more detail as well as our updated outlook for 2023. Leeny?
