May I suggest that you at least, check out the cost comparison on a Caribbean cruise? We've been to several of the islands and find that most are geared to a younger crowd and pride themselves on dancing and night life. Having said that, many of the islands on which the resorts are located, especially those comparable to
Sandals (seen
here) soon become boring since, unless your into golf or scuba there really isn't alot to do, except eat. Trips into Montego Bay, or its equivalent on other islands, soon jades one due to the over-commercialization along with the dire poverty that's always just in the back ground. A good cruise line will take you to many different islands and the onboard friendships are a lot of fun... in our experience at least...
