We will be going in May with my ASD son who will be 6. He was 3.5 the last time we went. At the time, we also used the GAC and it really made the difference in our trip. I think that he handles waiting better now, and we plan to bring distractions. When we went in 2012, we did deal with a few meltdowns based more on lack of routine and food options than anything else. Towards the end of our trip he was begging to go home....now what kid begs to leave Disney World!?!?! Of course I am sure you have thought of this, but bring lots of snacks that she likes. My son lived on goldfish crackers and fruit snacks while at Disney. I found the link at the bottom on Disney's site, and it explains their new pass for guests with cognitive abilities. We had a different experience than the last poster regarding EMH. We found less crowds and the ability to walk right onto rides during those times. And be prepared for the HEAT! That was the worst sensory thing for my son. He does not like to be too hot or too cold, and he really disliked the heat and sweating. Take advantage of the AC whenever possible! I was thoroughly impressed with how my son handled Disney as a whole. We tried to prepare ourselves as best as we could, but we really enjoyed himself, and now he is super excited to be talking about going back in May. He loved meeting characters, and that was one place we couldn't use the GAC. Waiting in line to meet Buzz and Woody (his favorites!) for an hour, sent that whole day into a tailspin. But seeing the awestruck expression when he finally met him, made the meltdown worth it! We also made a picture book for our son by printing off different pictures from the web of the park icons, our resort, the airplane and airports, certain rides, so that he could associate himself with those things beforehand and was able to flip through it all before each day. One more thing....if you are planning to fly, my son had a very difficult time on the airplane on the way there. He pretty much cried the whole last hour of our flight. We sat at the very back of the plane and spoke to the person who shared a section with us and the flight attendants, and all were very understanding. We made sure not to over schedule ourselves so that we could have some spontaneous moments, but at the same time my son really liked knowing what was coming next. Hope some of that helped!! I am hoping to pick up some new information from more experienced travelers as well!
