I think we have had the most fun at Hilton Head island with the kids at the beach. We enjoyed it more than Destin. Get on vrbo to lease a condo. I think I paid around 1200 for a real nice 2 bed. The kids loved to ride bikes and they have a great rental program and trails all over the island. Great beaches out there too.
Some good places to eat but not much nightlife, of course we weren't looking for that. Fly into Savannah, spend one night there and visit the harbor area. They have some great resturants and its a cool old town. It's an hour drive to HHI from Savannah. Nice drive with all the giant pine trees. The golfing is great too. We went out on a catamaran for a cruise which was cool too.
I enjoyed it because it's a great place to go unwind and relax. We've been to the west coast many times and after dealing with the traffic and hustling all over to see Disney, universal studios, Rodeo, Santa Monica, San Diego, I feel like I need another vacation to rest up when I get back.
