Rob_K - Palomar is a definite - thanks for the links. The 'behind the glass' tours on offer are April to October, so I may miss that...
OneOfOne - thanks for the advice on the Cape - this is the sort of advice that is worth its weight in gold. Is KSC a single day exercise, or is it big enough to spend two days exploring? I couldn't find the cruise on Google - do you have a link for this?
Cheers
