I don't remember where I saw it (so I am *almost* useless!), but there are local companies that run busses to KSC. Try searching for the Orlando Visitors Bureau site. It was very expensive, I think about $55pp, not including KSC admission. Rent a car for the day and drive out. KSC is great! It's an easy drive, really a straight shot east, and the traffic isn't bad once you get past the airport (ditto for the tolls!). We really love KSC; unfortunately we only get there about once every other year...
