Ah the memories! I have been to most of the coastal locations posted here. I can't decide on a favorite. I love the snorkeling at Puerto Morelos south of Cancun but find Cancun and Playa del Carmen too crowded and unauthentic. I prefer Puerto Vallarta (older area not Nuevo) and Zihuatenejo for the ambiance and am waiting to try Huatulco. Hit the Cabo area shortly after the hurricane so although I will go back can't say it was a favorite. I also want to do an interior tour of all of the beautiful colonial cities. I absolutely love Antigua, Guatemala so I'm sure I'll find some new favorites. Hoping to be back in Mexico in 2021.
