All of the beaches from Cancun down through the Rivera Maya are public. You are free to swim and stretch out a towel where you want, even in the shadows of a hotel. Of course, the amenities are reserved for their guests. If you want the services – loungers, umbrellas, cocktail service, restrooms – at a very reasonable cost, consider a day pass at a beach club. The most popular is the Mandala Beach Club behind the Plaza Forum By The Sea. The price of admission includes a party atmosphere around the pool accompanied by DJ music.
