Group Attendee Housing

For your convenience, a group housing website has been created for international travel groups or other entities who plan to bring a delegation to the ASTRO Annual Meeting. The group housing website allows group organizers to reserve a block of three or more rooms for their delegation. If you would like to create a group room block, please contact Amanda Tokarski. Please note that the group housing website is for attendee reservations only. Exhibitors who need to request a room block must secure their reservations via the exhibitor housing website.
