I'm cruising (first time!) on the Oct 20 sailing from San Juan (Victory). I'm more interested in finding authentic places to eat on the islands than booking an excursion--any recommendations out there? We will be visiting friends in St. Thomas, so San Juan, Barbados, St. Lucia, St. Kitts and St. Maarten are the ports I'm looking for lunch suggestions. I browsed them in Fodor's, but I feel a little overwhelmed by all the choices. Thanks!
