We did the Family Magic Tour the week of Thanksgiving 2003 and one of the participants was using her ECV or
scooter...not sure which is which, but hers was the sit down type with a small basket in front...two wheels in the back. As we chatted while waiting for the start of the tour, she mentioned she could walk for short periods, but the scooter made it easier. We had a great CM that modified as we went so that everyone was included in the fun...and from the looks of this Grandma's face (I know she was a grandma cause she was with her granddaughters) I'd say she had a blast!
How did the CM modify the tour you might ask? Well, for instance, when we were trekking through the park, she made sure to find the ramps and easy access for the woman...no curbs or bumps. Also, when it came time for the woman to lead the group, she remained in her seat and danced in the chair like a ballerina...it was so much fun for her granddaughters and everyone.
I agree with a previous poster that a heads up to WDW when making the ressie might be helpful. You also might want to give a call the day before your tour to confirm that information and again upon check-in...it can never hurt.
If the CM or whomever you speak to says it can't be done, tell them phooey because it has been done!
Have a great time on the Family Magic Tour! It was one of our greatest memories from WDW...DS had his "first date" with Wendy on Peter Pan's Flight...
