We'll be going to Disney World in 10 days My dad needs double knee replacement surgery and will be riding an ECV. He can't stand for long periods of time. I don't really understand - are there some rides that will let you in an alternate entrance or a different line or something? All rides? All of the time? I am just trying to have a grasp on this before we leave. Should we still get fast passes for things, or will it be necessary? We are a party of 8. 5 adults, 3 kids. Seems like I've heard that only a party of 6 can stick with the one with a GAC. Are they ever lenient on this?
