Exhibitor and high level sponsors are the only renters entitled to meeting room space at the Marriott Marquis Washington, D.C. (ATCA’s headquarters hotel) and on the ATCA Annual Exhibit Hall floor at the Walter E. Washington Convention Center during ATCA Annual. Please book early to ensure you get the meeting/hospitality space you need. As we get closer to ATCA Annual, space options will become more limited.
