First trip to KSC! What should we know/see/do?

OK, so I'm a complete newbie to this stuff. We're going to KSC to
(hopefully!) watch the New Horizons launch -- we'll be there on the
17th but have to fly home that night so everyone cross your fingers for
good weather, please, OK?

So my question is -- what else should we see there? What's a "must
see", what's a "don't bother" -- should we plan on going there on
Monday for the sightseeing and back on Tuesday for the launch, or will
we have time to see everything on Tuesday?

What's it like watching a launch, anyway? I mean, not the actual
takeoff itself, but the part about getting there, fighting the crowds,
figuring out where the best place is to see everything -- any hints to
make it a better experience in any way? Should I bring all my camera
equipment or will I (as I suspect) be too overwhelmed watching it live
to even think about taking pictures? Any other touristy-type tips you
can share?

I know this is all old news to you s.s.h. regulars, but it's brand new
to me and I don't want to miss out on anything good. Also, I'm going
with a guy who's a real NASA hound, so I want to be able to act like I
know at least a little bit about where we're going to be and what we're
going to see and do there.

Help! I mean, thanks! I mean, thanks for the help!
