Thinking of taking a cruise from La Romana this January with Dominican family members. Some have US visas , some not. Any experience/info/advice on who can go on these cruises and what ports they can visit. The stops are Tortola, Martinique, St. Martin, Guadalupe. The ship is the Costa Fortuna, not a very highly rated one . Really appreciate any feedback, including any Costa Fortuna experience. Also, a reference to a local travel agent with experience.
