To gain access to scheduled talks and debates you will need to queue outside the venue entrances. If standing or queuing poses an obstacle for you, you can either purchase Fastpass tickets to the events you wish to see, or you can ask the Venue Manager or Venue steward for ad hoc support. In some cases they will be able to find a seat for you to wait on in the queue, direct you to a seating area and then let you in first before the event starts, or give you other advice based on your specific needs.
