Is Playa del Carmen worth visiting?
I'm planning a 12-night trip to Mexico for the first time, traveling solo. I'll be staying in Playa del Carmen for 7 nights, Isla Mujeres for 3 nights, and Cancun for 2 nights. I don't know how to drive, so I'll be traveling without a car. I'm looking for a place with nice beaches, walkable streets, and some activities to do, but I don't want to spend too much money.
