just in case you have a mexico city connection :
Fear Factor: 4.75
No one thinks twice about visiting our nations capital, and the same should go for Mexicos capital. In 2008, Mexico City had a homicide rate of nine for every 100,000 people, while Washington D.C. had a rate of more than 30 per 100,000 â€” over three times higher. Visitors to Mexico City should exercise the same precautions taken in any of the worlds big cities; sticking to busy, central areas and remaining aware of ones surroundings. Its very important to take only radio-issued taxis or taxis from official stands, never the â€œlibreâ€ (independent) or Volkswagen cabs, as there have been many instances of robbery and kidnapping. Dont walk at night except short distances on busy streets. This is an exciting city full of museums, art galleries and fabulous restaurants, not to be missed. Most people include a visit nearby to the majestic ruins of Teotihuacan, which are well patrolled and perfectly safe, with a visitors center and organized guides.
In Case your vacation or wedding is in Puerto Vallarta:
Fear Factor: 5
The lovely cobble-stoned hillside fishing village that was â€œdiscoveredâ€ after the filming of Night of the Iguana has spread at a dizzying rate, so that there are many Vallartas, including the original (still charming) town, the Marina and Nuevo Vallarta. Puerto Vallarta is filled with art galleries, which regularly throw open houses, gourmet restaurants and hotels in every price range. There are also the kinds of bars which encourage patrons to over-indulge, and thats never a good idea. Downtown Puerto Vallarta is safe to stroll, but never late at night after the festivities are over, and its not a good idea to venture too far off the beaten track. Thousands of Americans live here, and love it. The Costalegre coast, stretching from Puerto Vallarta to Manzanillo in the south, is very safe, as is the newly-named Costa Nayarit (a series of bucolic fishing villages) to the north.
Just i case you are getting married in Los Cabos
Fear Factor: 5
Cabo San Lucas, San Jose del Cabo and the â€œCorridorâ€ of resorts that stretch between them are like a backyard for residents of the southwestern U.S. Thousands of Americans live here on the southern tip of the Baja Peninsula (light years away from Tijuanas troubles) and the artsy little town of Todos Santos 45 minutes up the Pacific coast from Cabo San Lucas. Some visitors complain its too American in Cabo. The region is very safe, with good highways and busy downtowns. Visitors should stay out of unlighted side streets and stick to the well-traveled tourists areas, where shopping, art galleries and a big choice of restaurants make straying unnecessary. Swimmers must exercise extreme caution â€” the waters are treacherous and its important to know where its safe to swim and where not to even wade very far.â€
And now our main interest, getting married? visiting Cancun, Playa del Carmen, any point in the riviera Maya and Merida, just in case you want to go to Chichen Itza or Uxmal or simple the area:
CANCUN, THE RIVIERA MAYA AND COZUMEL
Fear Factor: 5
Cancun is one of Mexicos most popular beach resorts, which average around four million American visitors per year. Last year a retired Mexican general investigating corruption was assassinated by drug traffickers, but thats been an isolated event. Over-consumption of alcohol by younger tourists is a problem, and there have been rapes. But on the whole, Cancun is extremely safe. â€œThe leading cause of foreign tourist deaths in Cancun is heart attacks, car accidents and accidental drowning,â€ says Canadian writer Marlo-Renay Heresco, a Cancun resident who blogs about her life in Mexico on her website, atravelartist.com. â€œThe key to success when traveling or living abroad is exercising common sense.â€ The Riviera Maya (the Yucatan coast stretching south from Cancun) has little to fear beyond sunburn. The island of Cozumel off the Riviera Maya is a popular, very safe destination for cruise ships, where problems are the occasional purse-snatching or picked pocket.
MERIDA AND THE MAYAN RUINS IN YUCATAN
Fear Factor: 5
Although many people visit Chichen Itza on day-trips from Cancun, Merida is the gateway to comprehensive exploration of Uxmal and other significant Mayan ruins scattered across the state of Yucatan. Merida is a quiet, charming city, and the main ruins have well-organized tours and visitors centers, as well as guards. In addition to hotels in Merida, the Yucatan has a number of colonial-era haciendas that have been converted into small resorts. Mayan villagers are welcoming. Here again, its not a good idea to drive on unlighted roads at night, but central Meridas busy colonial-era streets are safe to stroll at night. â€œMexico is a large countryâ€¦ deciding not to travel â€œto Mexicoâ€ because of violence is like saying you wont go to New York because of a murder in Denver,â€ says Merida resident Ellen Fields. â€ Yes, there are places in Mexico where violence is on the rise. Where I live, Merida on the Yucatan Peninsula, and the nearby Mayan Riviera, has not seen this violence and is a very safe place to visit or to live.â€
to complement everyone comments, yes I live here and nothing to worry about had happen.
