Slightly off topic, but...I'd love to go on a cruise some time but not something like this.
There are some old boats with the old sales, like this one:

They make you actually do work and help out on these cruises which is much more fun than sitting at a pool all day and you learn loads.
I went on the boat pictured when it was docked in France and I can tell you it is wonderful.
