Planning our 1st WDW visit 3/26-4/1 with DH, 5 yr DS, 3 yr DD, can't decide if we should rent a car or use their shuttle service. We'll be spending all of our time at the 4 theme parks, to date we have reservations at AK breakfastosaurus, and dinner at Chef Mickey. Between these reservations and trying to see the fireworks and Spectromagic I'm concerned that the shuttle service might be too rigid.... What has everyone thought? When I called HIFS guest services, they were pretty vague about the scheduling...
