A major U.S. port is cutting ties with Carnival Cruise Lines, which is bittersweet for many travelers. But how will it shape this destination's future?

U.S. travelers are not giving up hope that cruises will one day return to a bucket-list travel destination in the Caribbean. For a brief period not so long ago, cruise ships departing the U.S. were able to offer travelers a simple, legal way to visit an island that had long been closed off to U.S. tourists.

The cruise line has an added fee that can get quite expensive and some passengers like it while others want it to go away.
