Marcia have fun on your trip, just try to avoid some of the 'danger' areas and with that I dont necessarily mean the ghetto's or downtown, just the places where there is the most tension between the Cartels and the government forces. Speaking from own experiences.

I love Mexico and I love Jamaica, never on my trips have I not gone downtown and Im not saying dont go to Mexico at all. Just avoid certain areas thats all and you'll spare yourself getting caught up in shootings or having to witness dead bodies stuffed in shopping trolleys or hung up in trees.

Mexico is beautiful country, there's just a lot going on in certain parts and it's good to be smart about it and do your research.

Have an awesome trip Marcia.
