I would not go there because of what was already said above, alot of crime....
we went to playa del carmen for our honey moon, went to apple vacation and had an all inclusive 5 star resort, and had a blast, I think it was around 2500.... we've been to Playa twice now and love it there.
Like John said above, if you can swing Hawaii, go there instead.... best vacation hands down that I've ever had... water was amazing, beaches were beautiful... just make sure to bring your wallet because that place is $$$
