Oh you dont go to the beach walking at night........you are a sitting duck if you do.
I havent but my dad has, dont know that their ideas of fun would match yours they just shop, and of course the tourist stuff,,,,be careful, when they went two years ago i dont know what the deal was but they were advised not to go on beach at night : actually told "beware of desperados"
I was in Cancun in 94 and i just loved it....visit the Mayan ruins and Xcaret.....and when you are done with that and since you cant swim go back to the obvious!!!!! LOL
