When we docked there last May we grabbed a taxi with another couple ($4.00 pp each way, taxi's are waiting outside of beach when your ready to head back to ship). We asked to go to Nachi Co Com, the taxi driver got us there in about 8 minutes. It was $28.00 for the day, with 1 hour of free kayaking or snorkeling and unlimited alcoholic beverages. You could also order food. The beach was beautiful with palapas and chairs. There was also a swimming pool and a bar. Our server, Manuel, was awesome, he brought us drinks before we even finished the first. We spent approximately 5 hours there and it was well worth it!
