I visited in December 2025. The weather was fine, but it was windy. I wore a long down jacket and went to see the dolphins, but the wind was strong and it was a bit cold. I was a little nervous about swimming with the dolphins afterwards, but once I put on my two-layer wetsuit and entered the water, I didn't feel cold. It was a little chilly when water got up to my chest while swimming with the dolphins. My friend and I had the whole place to ourselves, so we enjoyed playing with the dolphins without having to wait. I wanted to swim with the dolphins by sitting on their bellies, but unfortunately the dolphin assigned to us wasn't available yet.
We stayed in Dome Tent C, and the bed was spacious and comfortable, allowing us to sleep more soundly than usual. It was also nice to be able to see the scenery outside from inside the tent! The BBQ was a bit chilly due to the strong wind, but we had a windbreak, and starting the fire was a lot of fun.
Excellent service, convenient, I've used it 3 times already - I'll definitely use it again next time.
