when I was there, Playa del Carmen was an extremely pleasant place
where I did not take many pictures because I was wandering around sampling the invariably-superb margaritas and eating the world's best tacos at the Taqueria Gomez
(and yes I said "world's best" and yes I mean it and yes I'll go to the mat for that one, so if you have a problem with that I suggest you step up and say something).
the sea was a little ominous for much of the time we were there, what with tropical storm Stan blowing overhead (it wasn't a hurricane yet)
I'm afraid things are a little different now (AP photo, not mine):
