We are still torn about who to use for the ruins. Obviously there's the time factor, but we've heard such great things about Native Choice and they've been very responsive to my emails and questions, so pretty sure they're not fly-by-night. People rave about them. Probably I better decide soon or all the other DCLers will take the spots, lol.
I've heard some good things about the beach trips, too, probably a good choice for taking it easy. We live at the beach, so we don't do too much of that on vacation.

I hope you don't write the Stingray City thing off as a just a family excursion though... DH and I first went there on our honeymoon and loved it.
Really can't believe the trip is coming up so fast!
