Yes matey It was.. We stayed in Playa del Carmen in the Sandos Caracol..
I really really recommend it.. The culture is amazing. I went scuba diving off of the reefs and it is something that will remain with me in my mind. The people are friendly and cannot do enough to help.. (if you grease the wheels with a few peso's)
the wildlife is amazing.. we saw parrots, lizards, spider monkeys, fish, turtles, terrapins, racoons, badgers...
the only bit of advice I can give you that you really need to listen to is Mozzie spray! weapons grade mozzie spray!
swine flu is nothing to worry about.. didnt notice or see any signs of it.. just wash your hands with alcohol provided.
