T.C.
we just got back from there! love the beach and the pier and Ron Jon's - we haven't been there, but the zoo in Melbourne was highly recommended (I have preschoolers btw) - we didn't do it on this trip, but in prior trips we have done the kennedy space center - pay the extra money for the back stage tour - it is well worth it and you get to see sooo much more!
if you do go out to eat I recommend Coconuts for lunch or dinner and Simply Delicious for breakfast
we stopped in charleston on the way home for a few days (drove straight through the night on the way there) - kids loves it - not exactly on the way though, but it was fun and we had some time to enjoy it
I'm going to email this request to my friend who lives there to see what else she can add :)
