We took my MIL and wifes brother to playa del carmen march of 2023. My wife and i had some time in cancun ahead of their arrival. We rented a car and rented an apartment on the outskirts of pdc, went to grocery store to get food and cooked for ourselves some meals, ate all sorts of street food, walked around town and went to restaurants, public beaches, drove to some cenotes and swam, took a trip to chichinitza and had lunch and wandered around valladolid as well as a few smaller towns, etc. Its a cool area, if youre in an all inclusive I think you’d miss most of the good stuff, but if thats your cup of tea it seems that would be way safer than most US cities. Otherwise, while gritty outside the tourist areas, it did not feel unsafe, and people were very friendly especially if you try to speak a little spanish. There were folks that cleaned up the sargasso weed every other day on the public beaches, but on the off days it was certainly a thing.
