RushTix offers a very flexible system for our members. You can book an event and cancel anytime BEFORE the cancellation deadline.
The way our system works is that we send the guest list when the cancellation deadline closes. It's very important to cancel before that deadline so that another RushTix member can attend.
If you cancel after the deadline you will lose those tokens and your account may be flagged, which could result in the the suspension of your RushTix membership.
