We spent one gorgeous day on a large pirate-type boat with Danny's two brothers, their wives and the two grown children of the youngest brother.
The trip was with Junk Boat - Chantara which was amazing! The trip lasted all day and included snorkeling/swimming on Ko Ma reef, and a stop at the gorgeous Thong Nai Pan beach on Koh Phangan.
We were spoiled on the tour with frequent offerings of snacks, drinks and a buffet Thai lunch. The staff was wonderful! I highly recommend this trip.
