I always choose the restaurants that I want to eat at before we go, and have an idea of what we are doing each day mainly so we don't miss out the things we want to do, we always do fantasy land the first morning, and then in the afternoon do fast pass rides such as BTM.
I plan the studios before we go as because the shows are shown on a schedule, so I decide on what shows we are going to see and at what time so we can fit in all the shows we want to see.
