Booking within the group block supports the ATCA Global Conference & Expo. By booking within the group block it ensures your event remains financially viable and that sac. It also offers attendees a broad range of benefits.

Greater informal networking opportunities exist in the hotel within the group block (as this is where a majority of our attendees are staying).It will take you less time to travel from the meeting to your hotel room, making it easier for you to get to your room during down time.Any important announcements and information that ATCA may share with you at check-in is provided only within the group block.Any room drops arranged are only available to those staying at the hotel within the group block.You’ll get a reduced room rate (negotiated by the organization).

It is critical that all our attendees support ATCA by reserving their rooms within the group hotel block at the Marriott Marquis Washington, DC, for this event. ATCA receives a much-needed incentive toward convention expenses based upon the number of attendees staying overnight at the hotels for our event. If you stay in hotels other than ATCA's contracted blocks, your attendance does not count toward our incentive. More importantly, ATCA is unable to assist you should you have a reservation problem. 

By booking your room within the hotel block, not only are you saving your time and convenience being onsite, but you help keep registration fees as low as possible by helping ATCA keep costs down for the event.
