Hi-First time poster first time visitor at WDW FT. Wilderness cabins! I want to rent a cart 12/11/12-12/17/12. We have 2 adults 3 children (11,9,7). Can we get away with utilzing a 4 person cart, or do we need to spend more money and get a 6 person cart? Not sure of the campsite rules and didn't want any problems!
