Christmas in the Caribbean, how could you not have a good time? Well, pretty easily when there are so many little niggles.
Britannia is the biggest ship in the fleet and has both good and bad points. The good include plenty of deck space and sunbeds. Sure you will be packed like a sardine if you want to stay around the pool, but there are several quieter places if you look.
There was also lots of space inside in public areas and a bar or entertainment to suit most tastes. The atrium area was understated for a ship this size but still offered comfortable seating and easy access to bars and shopping on the different levels.
