Like traveling anywhere be cautious and prudent without paranoia. Try not be flashy, stay reasonably sober. All valuables other than pocket money should be kept in the safe in the office where you are staying. Don't leave your Rolex sitting on the toilet tank and have fun....I personally have had no problem on CC, My wife had some expensive earrings removed from her luggage at the old airport on our first trip...our fault really, should have been in carry on. Buy a couple pair of cheep sunglasses, leave the Ray-bans home.
