This year, we've invited my in-laws along to Disney World with us. They are both 80-ish and grandma will be in her wheelchair. We should be OK in our resort but I was wondering if anyone has experience and can offer suggestions and tips for navigating our way through the WDW transportation system and parks with someone who is wheelchair-bound. She can walk short distances so I think that we can park the chair some but she would be unable to stand in a line for more than a few minutes. She would definitely want to experience some of the low key rides.
