Want to kick your holidays up a notch this season? Instead of dealing with chilly temperatures back home, take the crew to the Caribbean with Celebrity Cruises in late December, and you can purchase tickets to an exclusive concert by Demi Lovato. The event will take place in St. Maarten on December 28, when a whopping four of the line's ships will be docked on the island.

Tickets are available on a first-come, first-served basis to passengers booked on one of four sailings: Celebrity Equinox departing Fort Lauderdale on December 19, Celebrity Eclipse departing Miami on December 21, Celebrity Summit departing San Juan on December 24, and Celebrity Reflection departing Miami on December 24. General admission tickets start at $100, and VIP tickets start at $300. For super fans, Celebrity is also offering a meet and greet.
