This forum gets quite a few requests for what to do, when one tires of the Casinos, and has done the beaches. It appears that there is a new attraction, which has just opened - August, 02, 2014. The Maritime & Seafood Industry Museum, at 115 1st St., Biloxi, http://www.maritimemuseum.org/
Obviously, I have not yet visited this attraction, but plan to do so, on our next trip to the Gulf Coast.
This might be something of interest, and especially for families, when something, beyond the beach, and the casinos is desired.
