The deadline to book rooms under the discounted DIA block has passed. To cancel or modify your reservation, review the information below or contact the hotel directly at 301.822.9200.


Please book your sleeping room directly with the Bethesda North Marriott Hotel and Conference Center. Should you find any other website that appears to be DIA Housing, or if you are contacted by any other agency that refers to the Advertising and Promotions Regulatory Affairs Conference and claims to offer lower rates, we urge you to use extreme caution and contact with their information. These companies often create phony websites that look authentic, but are not authorized to represent DIA, nor do they have access to officially contracted DIA hotels. Unfortunately, customers who book through these websites often arrive at their destination only to find that their existing reservation was cancelled by the agency at the last minute, leaving them without a room and liable for a steep cancellation fee.

Please Note: DIA will not be able to assist you with any problems or reservations not booked directly with the Bethesda North Marriott Hotel and Conference Center.

Should you have any questions or need assistance with your reservation, including confirming room availability, please contact Megan Stevens at
