Is there a minimum age requirement to drive the golf carts? We are going with a group of families which will include 6 teenagers, 11, 8, and 5 year old. I imagine that they would have a riot driving a golf cart around. Would hate to rent one only to find out that they are too young to drive. Disney has quite a few restrictions and twice my younger son has been disappointed to find out that he was too short to do something his older sister was allowed to do.
