I was there in March, and I saw many kids with heelys, and the only time I saw something being said something to about them if getting on the fairy to the MK, they couldn't wear them on the dock, b/c they will hang up.
I would like to make a comment about the heelys though on a different said rather than having them or not. When I was there in March, I saw many kids that were staying right with there parents with them. Many were hanging onto mom or dad's arm and letting them pull them along. My request is this, if your kids are going to wear heelys, be courious of other people. I was practically run over by kids using their heelys, no excuse sorry nothing, just knock into you or trip you and keep on going. When I was there the park was fairly crowded and not much room to go running and sliding as they were. I actually saw one kid using his heelys and when as he was he was looking behind him, and actually fell over a stroller. the parents appologized and appologized, but thankfully there was no children in the stroller. Just remember to be courtious of the people around you. Sorry if I offend anyone, and anyone with a rebutle feel free, b/c I'm sure there will be some, but I'm sure there are plenty who feel them same as I do. Again I say I like heelys I think tey are really nifty, my niece and nephew love them, but you have to be sinsible with them. If there would have been a child in the stroller, it could have hurt them, and no one wants to go to the hospital when they are at disney.
