To receive the special AOC rate, you MUST make your hotel reservation through AOC's online registration portal no later than 5:00 p.m. EST on November 3, 2017.  Do not contact the hotel directly to make your reservation. The AOC group rate is standard $279/night (plus tax) or the prevailing government per diem for qualified guests. 

IMPORTANT NOTICE: It has come to our attention that there are “convention services” companies that may be contacting AOC attendees to solicit hotel reservations for the AOC International Symposium. These companies have not been authorized to handle AOC housing and are not affiliated with the AOC Conference in any way. While it is not illegal for a travel firm or booking agent to solicit potential customers, it can be difficult to determine the legitimacy of offers from these organization. We strongly recommend that you do not provide credit card details to any phone solicitors. Please reserve your rooms directly through our registration and hotel process (link above) to avoid becoming the victim of fraud.
