My first cruise will be when I get married, and Carnival has just started posting the possible shore excursions. I was wondering if they usually sell out or if they are available when you get on board. I want to book some, but the money is kind of tight right now. I don't want to miss out on some things I really want to do, though. P.S. Any suggestions for shore excursions if you have been any of these places? I'm doing a Carnival cruise and our stops are: Dominica, Barbados, St. Lucia, St. Kitts, St. Maarten. (And St. Thomas, but I'm getting married that day

Thanks!
