Some sessions may allow you to sign up for a Waitlist if the session is full. A Credit Card on file is required to be added from the Waitlist to the Open Play Session. Players will be automatically added if an opening comes available before the start of the session. Players should drop themselves from the Waitlist at any time if they do not want to be added. If an Open Play session is FULL, there will be no changes to the roster once the session begins. Therefore, there is no reason for players on a WaitList to show up after a session begins in hopes they will get in.
