Things we love to do on cruises that other people don't? Take naps. I know a lot of people want to be all "go, go, go!" on their cruise, and not rest for a minute, but for the two of us, that's what our regular lives are like. And seriously, on sea days, being awake at 2-5pm is overrrated. The pool is a zoo, the sun is brutal, there's little else to do other than go to sales pitch presentations or be one of those couples that sits around being bored. Taking a siesta in one of the non-heated loungers in the thermal spa, or a shady spot of the pool deck, or even your own cabin is a great way to recharge, especially if you're normally an early riser but want to stay up late.
