Can't help you with the hotel, but if you need any advice on things to do in the area, feel free to email me.
For instance, there is a very nice area that opened up almost across the street from you since my last post here, Baytowne Wharf. They have some nice shops, restaurants, and a water taxi. Laso new is Destin Commons, which you can get to without getting into the horrid destin-proper beach traffic.
Hope your stay is enjoyable!
