The Goat Island thing threw me. Bolivar so Stingaree Marina. You didn't say if you were taking kids? Lot's of good ideas above. Willie G's is a Landry's. Definitely go see Isaac's Storm. Take crackers for the ferry ride. Lot's of good fishing on the jetties or just off the beach. Gaido's has been there for over a century and the food is excellent. They have a private club in the back called the Pelican Club. Sea Wolf Park if you haven't been exposed to a submarine. High end steakhouse on Offatt's Bayou is Number 13. Go enjoy the island.
