I've never sailed at Christmas time, but my love for Spirit-class ships is limitless. I'd choose one of those four lovely ladies over any other ship in the fleet, 10 times out of 10. Not only do they have my beloved bowling alley balcony cabins, but the layout of the ships is excellent. I love being able to walk all the way around the ship on deck 3, I love the plethora of little sitting areas tucked away in various corners, I love the not-too-big, not-too-small size and the way they never feel crowded. Big fan.
