If you can plan a few days away while you are in Biloxi, you might want to try and book a mothership trip to the Chandeleurs or, later in the fall, the marsh. I've fished with Capt. Troy Fountain aboard the Double Trouble and had some great trips. 2 1/2 days fishing, good food, meet some great people and have a wonderful time. Here is his site if you like to take a look.
Tight lines, Chris
