Hi,
My daughter has sensory integration dysfunction among other issues and is probably on the spectrum, although not diagnosed. She just turned 5 and we are taking a mother daughter trip in a soon. I am taking a light umbrella stroller because I know she will get tired, and she has no problem riding. If you have not checked the disablities board, please do. They have alot of valuable information.
I have gotten a Guest Assistance Card (GAC) a couple of times with her because waiting in line can be a nightmare. We only used it a couple of times where fastpass was not available, but is made for a much nicer experience. It does not let you cut in line, but it lets you wait in a much less confined area. I know our first trip, I was soooo worried about meltdowns and tantrums and just concerned about an overall miserable experience. But to my great surprise, she did really really well. She was a different child, really into the characters and had so much fun. She had a couple of tense moments, but all it all it was magical. Our last trip was even better, so I am really looking forward to this trip.
I understand about the fireworks. We did stay for them this time and my dd did very well. She asked me if we could go see Tink fly when we go back. I had to grin. I agree with Stacy, it does get better with experience. I also tell my dd about things in advance so she knows what to expect. It really makes a difference.
Have a magical trip. If you have any other questions I can help you with, let me know.
Denise
