I am coming to Orlando FL this July and, even though I have been many times, I am left questioning what to do. I am staying for one week - and I know that we will do Disney's Magic and Animal Kingdoms, as well as Universal's Islands of Adventure. Those 3 parks are a given. However, I am not decided on what would be best to do with the rest of the week. Should I keep parks to 3? If not, what others should I do? Water parks even? Epcot? Idk. Advice please
