If there is no room available ask about the wait list. I waited 4 hours for a room because the kids at the front desk failed to mention the wait list option!
Champions was horrible, especially the service. Took over 40 mins to get my food when the restaurant was mostly empty. I should have gone to Chili's and suggest you don't make the mistake.
BWI Airport Marriott is ideally located just one mile from Baltimore/Washington Thurgood Marshall Airport, and provides a complimentary shuttle service. Arundel Mills and Maryland Live! Casino are close by; downtown Baltimore is a 15-minute drive.
