Chief Financial Officer and Executive Vice President, Development at Marriott International
Thank you, Tony.
Our first quarter results reflected robust demand growth around the world with all regions and all hotel tiers posting solid performance. U.S. and Canada RevPAR grew 26% year-over-year; occupancy reached 66%, up 8 percentage points; while ADR rose 10% versus the year ago quarter. International RevPAR rose a remarkable 63% over the '22 first quarter, with ADR rising 16%. Occupancy reached 64%, an 18 percentage point improvement versus the prior year quarter. Demand was strong in all international markets with particularly impressive improvement in Asia Pacific after travel restrictions were lifted.
RevPAR in Greater China was 95% recovered to pre-pandemic levels in the quarter and Mainland China was more than fully recovered. This is all the more notable given that demand in the quarter was overwhelmingly driven by domestic travelers as international airlift was still less than 20% of 2019 capacity at the end of March. As you will recall, around one-quarter of room nights in Greater China were from international guests pre-pandemic. International flights to and from China are slowly being added, although airlift is only expected to be around 40% of 2019 levels in the second quarter.
Total gross fee revenues totaled $1.1 billion, nearly 40% above the prior year quarter with a meaningful rise in incentive management fees, or IMF. IMF nearly doubled compared to 2022 to $201 million. They also topped the first quarter of 2019 by 23%, with every region except for Greater China earning more incentive fees than in the 2019 first quarter.
Our non-RevPAR related franchise fees also grew meaningfully once again, totaling $197 million, up 16% year-over-year, primarily due to co-branded credit card fees rising 18%. Containing cost remains a focus at both the corporate and the hotel level. In the U.S. and Canada, margins at our managed hotels rose 2 percentage points versus the 2022 first quarter and they remain above 2019 margin levels. Adjusted EBITDA totaled $1.1 billion, a new quarterly record despite the first quarter being the seasonally-slowest quarter of the year.
Now, let's talk about our 2023 outlook, the full details of which are in our earnings press release. With the better-than-expected first quarter results and robust global booking trends, we're raising our full-year guidance. Macroeconomic uncertainty is not impacting our short-term demand and trends across all customer segments remain strong. The second quarter is expected to benefit from particularly strong year-over-year growth in international markets, especially in Asia Pacific. However, there is less visibility in forecasting the Company's financial performance for the second half of the year.
The high end of the range reflects relatively steady global economic conditions throughout the remainder of 2023 with continued resilience of travel demand across all customer segments and markets. The low end of the range reflects a meaningful softening of the global economy in the second half of the year with worldwide RevPAR in the last two quarters roughly flat compared to 2022. For the full year, RevPAR in the U.S. and Canada could grow 6% to 9% and international RevPAR could grow 22% to 25%, leading to global RevPAR rising 10% to 13%.
Total fees for the full year could rise between 13% and 16% with the non-RevPAR-related component increasing 4% to 7%. Non-RevPAR fee growth is expected to benefit from higher credit card fees resulting from growth in average spend and in the number of cardholders. We still expect G&A expenses of $915 million to $935 million, an annual increase of 3% to 5%, but still below 2019 levels. Full-year adjusted EBITDA could increase between 13% and 18% and adjusted EPS could rise 19% to 26% above 2022.
Our powerful asset-light business model continues to generate a great deal of cash. In the first quarter, our net cash provided by operating activities was around $890 million and we returned over $1.2 billion to shareholders through the end of March. Our capital allocation philosophy has not changed. We're committed to our investment-grade rating, investing in growth that is accretive to shareholder value, while returning excess capital to shareholders through a combination of a modest cash dividend and share repurchases.
For the full year, we still expect 2023 investment spending of $850 million to $1 billion. This includes $100 million for the just completed acquisition of a City Express brand portfolio, as well as higher-than-typical investment in our customer-facing technology, which is overwhelmingly expected to be reimbursed over time. With the increase in our adjusted EBITDA forecast, we now expect to return between $3.6 billion and $4.1 billion to shareholders in 2023.
On the development front, we are sure many of you have questions about the banking environment in the U.S. and in Europe, in particular. Given rapidly rising interest rates, the financing environment in these regions has been challenging for some time. Another element of uncertainty has now been added as some banks wait for more clarity around capital requirements and perhaps additional regulations. However, while there are challenges with lending, especially for new construction projects, deals that have committed financing continue to move forward. Additionally, the number of deals leading the pipeline is not increasing. Fallout in the quarter was around 1.5%, below our historical average of just over 2%.
We're closely monitoring the situation and the regulatory response, but we do expect the tightening in hotel financing to be short term. As we have seen over time, hotel financing has proven to be quite resilient over the long term. Hotel loans have been among the better-performing sectors of commercial real estate lending of late as hotels continue to post excellent operating results.
I'll now turn the call back over to Tony, who has a few more comments before we go to Q&A.
