From Ko Pha Ngan to Santa Cruz, full moon parties have become a global institution among nightlife revelers. For its third year running, the Ace moves the concept from the beach to the pool and amplifies the drum circle component by forgoing DJ sets altogether. For three hours, partygoers are encouraged to beat drums, which, along with flutes and didgeridoos, provide a soundtrack for belly dancers to do their thing. Outside the circle, tarot card readers and fortune tellers give donation-based readings, while massage therapists provide $12 mini treatments, including chair and watsu massage, reflexology and cranial work. Estheticians are also on hand to dole out free face masks to this all ages crowd, who often roam the party with their mugs slathered in the detoxifying concoction.
