Okay. If you are looking for an affordable way to snorkel at Fun or Mot Island, this is it. The tour guides are friendly and rather helpful. Booking the tour online is easy. And they do have people responding fast to your questions. Mind you this boat tour is not as "deluxe" as the pictures show. There is definitely no sunbathing on the top deck of the boat, not on the boat I was on anyway. And the "small group" means about 25 people on the same boat. While the water around the two islands are clean, but there were too many fish on the day I visited.
Overall good value for Snorkeling and lunch. The guides were OK, however the sites on the reef were crowded w/ many boats--- thus too many snorkels and divers in 1 spot--
Also the reef was either dying or dead--- very little color. Lunch was Vietnamese tasty! Would probably not snorkel at that location again.
