That is the only advantage about FL being flat. You can see things like the shuttle from anywhere in the state, just about. We live in Tampa and watch it all the time. From Disney you just need to find an un-obstructed view, as much as possible, looking East and slightly south, then look up and you'll see it. If your in town I would recommend hopping on the East-West Toll way or one of the now many roads that head over to the East coast and get at least to I-95 and find a spot. The experience is much much better over there as you can feel the power. The only challenge is that the probability of delay is always High so you could spend valuable vacation time, but if you are into give it a try.
