International info and travel tips
Several companies unaffiliated with the AAD or Experient, Inc., have been posing as the official registration and housing provider for the 2020 Annual Meeting. These companies may contact you directly to offer registration and/or housing for the Annual Meeting through websites designed to deceive visitors by posing as an AAD website.
Do not give your credit card information or make any reservations with any website other than our legitimate registration and housing partner, Experient, Inc.
