Just booked our hotel for our first big family vacation, and we are going to WDW! We have a 7, 5, 3, and 1 year old so I'm sure it will be stressful as well as fun. Staying july 2-11th, 5 days of WDW, and we are aslo going to visit Legoland and Seaworld.  Any tips for a first time Orlando visitor, or park tips?
