We are thinking about a Disney trip in September. This will be our 5th time so we've seen pretty much everything and were wondering if we can shake things up a bit and also do Universal/SeaWorld. We usually stay onsite at Disney and don't rent a car. Is there an easy and not so expensive way to get from Disney to Universal/Seaworld? Or would we be better off staying onsite at Universal for 2 or 3 days and then switching to Disney? If so what's the best way to change hotels? Help!
