A few months ago I took down suggestions from the boards on HH restaurants.
DVC member favorites included the Old Oyster Factory, which has a deck with a view. I believe this is a family restaurant but I haven't been there.
Other recommendations are the HH Diner, the Cracker Barrel, Dunes Pizza, the Crazy Crab (someone's choice for "the best"), Crane's Tavern (steak, expensive), Spartina's (also expensive, I think)and Wild Wings. There are also several restaurants on the other side of the marina, just over the bridge from the resort.
At HH we love to cook out on the grills. There are quite a few of them. The Piggly Wiggly supermarket is just down the street. Also, I think in your information packet you'll receive the names of several restaurants that deliver to the resort. Our first night there, ever, we ordered Chinese takeout from I can't remember where. It wasn't great, but it did appear at the door.
I don't have kids but other members also say that HH offers many activities for children.
Hope this helps. Have a great trip.
