Please note that the Marriott World Center Hotel and Convention Center booking deadline is May 1, 2026. Kindly note as well that the majority of rooms at the group rate are available over the main conference dates. Those dates are for arrival on Tuesday, May 26 and departure Thursday, May 28 (Tuesday and Wednesday nights).    Pre- and post-conference nights have limited availability at the group rate. If one night in your date range is unavailable, the system will show that no dates are available. Adjust your booking to only nights that remain available to reserve your room at the group rate. You may also need to call the hotel directly to secure shoulder nights.
