Cruises to the Caribbean are priced the highest during the December holiday period - Christmas through New Years. Prices are lower in January and rise again in February - April as the people living in the colder parts of the country seek warmth and a getaway from snow and ice. Prices are also a bit high in the summer as families take vacations; since many of the ships are sailing in Alaska and Europe in the summer availability is somewhat scarce. Book your cruise as soon as possible during peak times to ensure the lowest pricing. Enjoy!
