Some of these rides like POTC and IASW give time-slot tickets because of the safety rule allowing only one physically disabled guest on the ride at any one time. Even though my DD1 is not in a wheelchair he is only allowed on the adapted wheelchair-friendly boat on IASW because his mobility is impaired and safety in an evacuation could be an issue. Other rides like Parachutes he is not allowed on at all because he could not evacuate by a ladder. Once he was not allowed on Peter Pan for the same reason although he normally rides it. Some of the rides like POTC and IASW, where there may be a degree of wait due to the length of the ride despite the ticket system, have benches to sit on. The one fault I find with the new Ratatouille ride is that there is no ticket system for disabled guests or benches to sit on. Disabled guests have to file in along with the fast passes but then while the fast passes go through the turnstile and quickly on to the ride, disabled guests are directed to the side. As there is no ticket system you can get to this point and then find that there are other people waiting already. The wait here can be really long but there is nowhere to sit which is very hard for those who find standing difficult and/or tiring.
