Frommer's "Strong currents run through the pass, but you can safely swim in the Gulf or watch a brilliant sunset at the Pass-a-Grille's public beach, just one door removed"
Fodor's "The resort offers several one-bedroom cottages as well as a three-bedroom cottage that make it a great place for families who want to enjoy the beach life (the three-bedroom has a private pool)"
