Hi, I have twins and one of them has autism. they are 6 years old and we are going to Disney World and I am looking for a stroller that will fit both of them, but my one child is about 80 pounds, so we need one that could hold at least 130 pounds. We are looking for something thatHe can "cocoon" himself in if he gets over stimulated at Disney World or the airport and also just so they have a place to rest since it will be alot fo walking at both places. Thanks
