I just had to come back here with my family to visit the beautiful Playa Del Carmen. Not only a pretty coastal resort town, it's loaded with great sight-seeing, amusement parks, natural geographical wonders, ancient structures, relaxing beaches, shopping, night-life, and gorgeous resorts. However, it is an extremely popular tourist destination so be prepared for crowds!
You will see Paradisus Resort, Sac Actun Cenote, Xcaret, and Tulum.
