People are misinformed. The beach at Pearl is clothing optional and always has been. Pearl is about a 20 minute walk on the beach to the North from Puerto Morelos. Beaches in Mexico are public beaches so you may get people from another resort walking by but the security at Pearl keeps them walking. The only restriction is that you are not supposed to have sex on the beach. We have been three times this year. We go about every 4 months or so.
