At least you got them Beavers... http://www.cnn.com/2008/WORLD/europe/11/21/scottish.beavers/index.html
If you book the Xcaret package, it usually includes your transportation there, and back... I know mine did. It's over an hour away from Cancun.. Took a little bit to get there..
me and a few of the lads are going to Xcaret while we are there its not too expemsive and i doubt we will ever get a chance to go again.... this old geezer came into my workshop yesterday and said he had been there and done it and said it was incredible... the lot of us will be going for sure...
