Has anyone else used PlayaKids.com? My wife and I had a great stay with the kids (9 and 6) at Playa del Carmen in April, made even better by the 2 parents' nights out that Playakids gave us! If you have used them, consider reviewing them on-line.
Our sitter came right on time, jumped through hoops for us, and took great care of our kids.
And was much more reasonably priced than what our hotel offered!
