Everything was arranged comfortably. Breakfast was simple: toast, juice, coffee, tea, and bananas. Lunch was a Thai buffet, and water and cola were unlimited during the boat trip. There were two snorkeling spots, each for 40 minutes, and we happened to see sea turtles. We had a full two hours at Koh Nang Yuan, which was just right and very comfortable. The only downside was that the boat was quite crowded, making it a little cramped. Remember to take seasickness medication; the boat ride was very bumpy, and the waves were huge when the weather suddenly changed and it started raining.
