link to the original post mentioning the start of the program. As far as I know, it was just including wheelchairs, not strollers, but even if a wheelchair is too large for your child, at least it would help you get to where the strollers are rented.
I can't remember which thread it was in, but a couple of people posted that they had used the wheelchairs from the parking lot and found it helpful. Hopefully, one of them will post here.
Here's some pixie dust for a great trip. Tell your DD that we have met Snow White and she is just as sweet in person as in the movie.
