I actually didn't use my lanyard (being a female I felt a bit dorky wearing the cruisecard around my neck and easily kept it in a pocket instead.
The staff were outstanding and really got into the Christmas spirit, wearing Santa hats, etc. and the whole ship was decorated, especially the Atrium which looked magical, especially when "snow" was organised.
Everyone had a little Christmas stocking with sweets on our pillow instead of the usual chocolates on Christmas Eve.
We didn't know whether we would enjoy the cruising life (especially my active husband who doesn't usually like being constrained in one place), but there are so many areas and things to do neither of us felt this way at all.
We have spoken to a lot of people since returning, and many friends say, "cruise ships are just like floating RSL clubs". These comments always come from people who have never cruised, and I just tell them it couldn't be further from the truth.
We are planning our next cruise (or dreaming at least!) for 2012.
