Most of the rides will hold 1 adult and two children..so you will be riding two and three...only ones with tight fit maybe Dumbo, and Goofy's Barnstormer but we have riden them with 1 adult and 2 children. Alot of the boat rides will accommodate five ( ITASW, POC, JC, Maelstrom, Kali River Rapids) Mission Space only holds four but you can split up with two and three. You may run into trouble at R&RRC as the seats are two by two and I wouldn't want a small child to be with a stranger or by theirself on that one. Good luck and have a Great Trip.
