We love Top Sail, St. George Island or St. Joseph Peninsula. We particularly love Top Sail because it has full hook up, cable and a paved bike trail outside which can be rode for quite a ways, especially to Seaside which is really neat with food trucks, shops and dining. Additionally, it is also not far from Pier Park (I think that is the name) which is very nice complex with restaurants, shopping and kids activities.
St. George Island and St. Josesph Peninsula are much more secluded and laid if that is the type of atmosphere you're looking for.
We stayed at St. George Island last year for Thanksgiving. It was beautiful but in hind site would have preferred Top Sail.
