I am getting maried here in Feb. I have absolutly no worries. I think Matt put it wonderfully in a different thread when he said. 70% of Mexico's Tourism dollars come from this area. They are going protect it. And Honestly Guys....
W Said " I know when I went to Cancun 2 years ago our hotel recommended us not to go out side hotel zone after 10pm and also not to attend clubs or bars outside the hotel zone" I wouldnt go out at that time in some areas of Milwaukee, where I live, Or Chicago, Or New York, or Shanghai or Bejing .... Everywhere has crime. If your smart you will be fine. I'd Listen to what Matt said in the above Forum from La Luna. He doubt he would put his lovely wife in danger. Stay where your told. Don't be a loud drunk, respect those around you. Chances are, you will be as safe as you would be anywhere else in the world.
