Disney has always been so accomodating, but when Rachel was an infant and we did not know about the GAC we had so many problems. Other guests did not care that we and our special baby needed a seat on the bus so she would not just slither out of our arms. She is so floppy, and it is very hard to hold such a baby securely if standing on a moving bus. Things changed once we were able to obtain her wheelchair/stroller, and it became obvious to most people that she has special needs.
