We're staying at the Radisson Parkway. They have a shuttle to Main Gate (is that DD?) Let's say we get to the Animal Kingdom and want to go to Epcot. In the past we've always stayed on property and went back to the resort for a break before going on to another park so I've never paid attention to other buses at the parks. Can you get from one park to another directly or do you have to go to a resort to get another bus? The Radisson shuttle runs only once an hour, from my understanding and I don't want to waste a lot of time waiting arounbd on transportation. We will not be renting a car.
