It was a fantastic tour. They picked us up at the hotel in the morning, and we went parasailing and sea walking at each base on the way to Koh Larn. On Koh Larn, we got to try jet skiing and banana boating. Each activity wasn't long, but it would have dragged on if we'd done it longer, and we could have done other activities for an additional fee, so I thought it was a well-balanced tour. Lunch on Koh Larn was delicious, and we had three hours of free time. We chatted, drank, and took naps with the people we made friends with during the tour, which was a great way to unwind. I highly recommend it. The tour guide was also very kind, so I highly recommend it.
