I almost always pre-book any excursions we want to take. Other than that, we just go with the flow. We don't hang out by / in the pools or hot tubs--I don't relish the idea of sharing a pool with hundreds of people I don't know--
I usually find my spot where it's quite so I can just plop down and relax and let the world go by.
I don't watch the news, don't call home to try to get bad news ( bad news will always find you )--I just might get concerned if I saw a couple mushroom type clouds on the horizon--but then again, maybe not!
Cruise to rest and relax--don't cruise to stay wired up and connected to something at home or work you can't do anything about anyway !!
