Was fun to do. The island itself is ok, but you get a little more feel for the area if you get off of the main road and away from the sales folk. We didn't get to do the air sailing due to winds but we did stop for swimming. A little drinking fun as well. Overall, I would recommend the trip if you are wanting to meet a few folks.
This is more of a problem with Chichen Itza than with the tour. Was ruined a bit by people trying to sell things constantly and that a lot of it was off limits now. It was not a bad trip, and if you are going to Chichen Itza then this tour should be good enough for you.
