A couple of years ago I went on my first cruise which in it's self is an adventure everyone should do. But the most awesome adventure I had was when I went scuba diving on one of my shore excursions in the Grand Caymans. My only regret was that I didn't do this 20 years ago. And the crazy part is, I don't even know how to swim. So, if you ever have a chance to scuba dive jump at it because you will love it.
