Very nice, but that jet flight would kill me, the Caribbean has a lot to offer, if you know where to go.
Have fun, take lots of pics, I'm sure it's a trip of a life time. Oh, do yourself a favor, check lagoons and tidal pools for some incredible stuff, you won't be disappointed, but you'll hate your self for no being able to bring it all home! Take pics, pics, pics. Enjoy your trip, be safe!
