Very enjoyable experience for 6 adults, 5 teenagers and an 8yo. Guide speaks English well. Was friendly and happy to be with us. Crew was also good. Instructions were clear. Buy new snorkel mouthpieces if you wish. We didn't bother. Will recommend getting beach slip on shoes as beach had sharp shells. We didn't. Was OK but would've been better with shoes. Buffet served was really delicious and a good spread. There were halal and vegetarian options. We really had a good time. Crew was very attentive when we're snorkeling making sure everyone was safe and comfortable. Drinks and snacks avail on board. Don't bring too much cash or valuables for safety reasons as bags are hard to watch when you're having fun. There's about 30+ pax in the speedboat. We paid 2000+baht additional on board to book a private long tail boat at one of the islands. They bring you out for photos and snorkeling away from the crowds. Bring extra cash for that if you wish. Would highly recommend.
