Is Cancun safe?
Cancun is as safe as any other tourist place in the world. I think wherever you go as a tourist there are certain precautions you need to take like respecting the locals customs, not getting drunk to the extent you cannot manage yourself, not travelling alone, be in public places at night. Follow these and you will be safe in any tourist place. I am planning my cancun trip as well and creating my itinerary at http://www.triphobo.com/cancun-mexico, I am not much worried about the safety factor, as I do adhere to the above points everywhere I go. I have not been in trouble till date..
