The Sheraton and the Hilton are the two premium high rise hotels that are sea side. They will both give you excellent access to the beach and are beautiful hotels. The Holiday Inn is another option too. We have family nearby and rarely stay at the island otherwise I could give you some more specifics on lodging. Condos are available and there are several services that book them for you. You may want to review http://www.sopadre.com/index.php. A kid friendly restaurant that is quite popular is Blackbeard's. In the event that you can get away for a romantic adult evening I recommend Scampi's Restaurant. Another good family friendly establishment is Sea Ranch Restaurant. Have fun!
