Love BB-8, Marty McFly, and Elsa? Ok, but do you love them enough to take a Star Wars, Back to the Future, or Frozen-themed cruise? Plenty of people do, and we’ve rounded up our favorite options. Some of them have already sold out (like we said, people love a pop-culture cruise), but themed itineraries are popping up all the time. Could a Revenant cruise be in our future? We hope not.
