Shore fishing in the Caribbean

[ScottM]

Me and the Mrs., along with my brother and his wife, have booked a cruise with Celebrity out of San Juan P.R. in mid-January. We're headed to Antigua, Barbados, Grenada and St. Thomas. Any of you guys heard how good the shore fishing is down there? I'm thinking of bringing a spinning rod along if it's worth the effort. All the travel guides mention offshore fishing, but that unfortunately is not in the budget.
