Due to COVID-19 restrictions, in person registration for the ACES 2021 conference in Atlanta, GA October 5-10, 2021 will be limited to 950 participants. To accommodate presenters, registration will initially be opened only to accepted presenters and the registration link will be included in the proposal acceptance email, which is scheduled to be sent on Friday, May 7, 2021. Registration will be on a first come, first serve basis for presenters. For presentations with multiple presenters, it is highly encouraged for at least one person from the presentation to register ASAP. No presentations will be cancelled if some members of the presentation team cannot register. Based on communication from the Hyatt Regency, it is expected that social distancing guidelines may allow for more registrations to be added in the future, but the timeline is not guaranteed. The Hyatt is following the current CDC guidelines of 6-foot social distancing to ensure attendee safety. ACES appreciates your patience and communication will be forthcoming guidelines are changed.
