Doug, don't try to do both Disney and Universal in 2-3 days, pick one or the other. Disney has four separate parks plus two water parks and Downtown Disney--plenty to occupy your time. Universal has two separate parks and a central entertainment area. The nice thing about Universal is that if you stay in one of the on- property hotels, you get a VIP speed pass that lets you go to the front of the line on every ride. Worth it's weight in gold!!!!! Plus, the transportation from the hotel to the park area eliminates a whole lot of walking. Disney has a Fast Pass, but it's really only a reservation system plus you still end up waiting in a line.
