I have reservations. I’ll be there in 6 weeks.
I have been there many times and taken the ferry over to Cozumel plenty and never had an issue. For the most part it is safe. Just don't wander off into the jungles.
It’s very pretty down along that coast. We saw the Voladores (those guys that fly from a pole, tied by their heels). There’s a little Posada de Amor in Puerto Morelos north of there, quite lovely. We stayed there, thought we were leaving Saturday but it was actually Sunday. We just totally lost track of time.
