How to spend a day at KSC?

DELURK

On an upcoming work trip to Orlando, it appears that I will have
commitments on Sunday evening and then Tuesday, with a "dead" day in
between. As a modest space history fan (who has appreciated book
recommendations and other nuggets on this forum), I thought I would
take that Monday to drive to KSC, where I have never been.

So, with just 1 day to work with (maybe just 3/4 of a day, since I will
need to begin and end in Orlando), how should I spend my time (and
money, which I wouldn't mind spending for this cause) to see the most
neat stuff? Preferably technical and historical stuff? It looks like
they have a variety of different tours and tickets to choose from. Any
pointers like "be sure to look for this neat artifact in such-and-such
corner on this tour" would also be appreciated.

on, or should I stick just to things at KSC?
