Planning on going to Puerto Rico at the end of August with a 19 and 24 year old. Decided on the El San Juan because of the nightlife. They want to be able to do something in the evenings at the hotel. My question is can the 19 year old get into the clubs at night. I know the drinking age is 18 but on a site recently visited, a comment was made that indicated the clubs can set the age at 21. Does anyone know if this is true?
