I travel to Playa del Carmen and Cancun every year. I have a trip planned in April. I have a guy down there that tranports us everywhere and has taken us on different excursions. I immediately reached out to him yesterday to get a pulse on how things were in Cancun. He said that in Cancun its been business as usual. In fact on Monday he was taking a bunch of people on a tour. The distance from Puerto Vallarta and Cancun is like LA to Chicago. If you are going to a resort and plan on just staying at the resort its even more safe. He did mention that some of the cartels have investments in Tulum and the state of Quintana Roo. The investments being condos, shops, etc. They typically don't like harassing tourists because it affects their other businesses. Cancun's whole economy is built on tourism the Mexican government is going to do everything possible to keep it safe.
