They are both neat RV Parks I like the Silver Slipper-- right on the gulf.
We spend our time in Gulfport and while traveling Hwy 90 in Biloxi and Gulfport you'll find motor homes stopped all along the beach, for short periods, in areas that were Casino lots that have moved their facilities across the street onto solid land. If you travel on 90, going west, when you cross the newly rebuilt bridge to Bay St Louis take a left at the traffic light at the immediate end of the bridge. Stay on that road and you will dead end into the Silver Slipper. The RV park is on that road just 1/4 mile before the Casino.
Good luck in the Casino's and the food is superb in both Casino's in Bay St Louis,
