This tour takes a 35 min ferry drive to Playa del Carmen and from there it is only a 15-20 minute drive to the caverns. It is a nicely upkept park with an impressive cavern system. You will get a helmet and flash light, and then it is off for exploration with the local cavern guide. There are light systems, bridges, stairs...all around and you will even have the opportunity to swim in the cavern (life vest provided), which is an exciting experience underground in the fresh water in the middle of the jungle. If they still go to the same beach, it is a nice buffet with bar available, swimming is nice such is some snorkeling and sometimes they got jet skis or parasail available..good luck in the Mayan Riviera!
