Petit Saint Vincent: The entire island is the resort, the resort is the island! Take a brief vacation and enjoy the relaxing sights and sounds of PSV. Ah, I feel better now. Petit Saint Vincent is a 122 acre private island resort located a 45 minutes boat ride from Union island in the Grenadines. The resort features few widely scattered guest cabins giving extreme privacy. An attentive staff makes for a great and relaxing vacation.
