Preparing to Attend an ACS Meeting
After you register for the meeting, you should complete the visa application process, use ACS meeting & event resources to plan your travel, reserve your hotel room, and create your schedule. To save money and assure you receive proper accommodations, we strongly recommend that you complete your hotel reservations and register for the meeting through ACS before the deadlines.
All attendees, including speakers and poster presenters, must register for the meeting in order to participate in the technical sessions or the Expo. Attendees must display their badge at all times to be admitted to all official ACS sessions and events.
