Relative to Xcaret and our experiences there, my opinions are as follows:

1) Worth it? No. The price of admission is very high and the value for price paid frankly isn't there. Food and drink are also expensive; they did have a "meal plan" option when we visited. Wasn't impressed with the food in the park but the beer was cold. Oh and by the way you are supposedly not allowed to use your own sunscreen and must buy their (high priced) sunscreen which is approved for use in the waters inside the park.

2) The evening folkloric show is extremely well done. It may be too intense for young children though. Having a basic knowledge of Mexican history is helpful to understanding the show especially during the first half of the program. The second half focused on music and dance from the various Mexican states. La Cochinita got her degree in folklore at Mexico City's national school of fine arts and said that the dance performances were excellent. Oh yeah, it helps a lot if you can understand Spanish; there wasn't a whole lot of English translation going on during the show.

3) La Cochinita and our son did the "underground river" swim - which like just about everything at Xcaret was an extra cost. First off, the water was very cold. And the so-called underground river was constructed for the park. Not much in the way of snorkeling in the lagoon (also artificial). You'd be better off hiring out a boat to visit some of the reefs offshore of Cancun or Cozumel instead.

Finally what kind of annoyed me was that Xcaret advertises themselves as an Ecological Park. Uh, ok, but how about the fact that the developers basically came into this part of the coast and tore up the land to build this thing? Not so ecological in my opinion.
