Regerding tours at KSC: There are two types, the bus tour included with the standard admission and the "special" tours that require an added fee. The standard bus tours run pretty much continuously all day; you just go over to the waiting zone and get on the next bus. This tour stops at the observation gantry (from where you can see the shuttle launch pads and the locations of the 'historical' launch pads from Mercury, Gemini, and Apollo launches) and the Saturn V rocket facility, which includes two 'movie' type exhibits as well as many moon mission related items, plus of course the awe-inspiring Saturn V rocket that was scheduled to go to the moon! You also drive by the vehicle assembly building and the Shuttle landing strip. This is a great tour and will complement your touring of the Visitor's Center. Additional tours (at additional cost) require "reservations" for specific tour times. Some include visits out to the historical launch pads or tours of the Space Station facility. We have done them and while interesting, if I were spending the extra money I'd spend it on the IMAX movies at the Visitor's Center rather than on additional tour stops. At the Visitor's Center, don't forget to walk thru the rocket garden; there are mercury, gemini, and apollo capsules to (try to) sit in and a walk-thru of the white room, in addition to a bunch of rockets and cool info. Also, go walk thru the shuttle mock-up and the astronaut memorial area. I think your kids will have a great day at KSC! (BTW, IMO there is NOT time to do both KSC and Astronaut Hall of FAme in one day, so don't spend the extra money if you'll only have one day's admission!)
