I had a great experience doing the open water course with Ana. Smiling all through the course and making it very enjoyable. Would recommend diving at good time for a good time.

I had a fantastic time on Koh Tao, and I spent a large part of it at Goodtime. I started with a refresher course with Ryan. He did a great job, and it was simply wonderful to be underwater again. The next day, I continued with Perfect Buoyancy with Lukas. It was an amazing course. Afterward, my position in the water was so much better. That night, I did a beautiful night dive with him. The following morning, I did two fun dives with Lydia. Finally able to maintain my altitude, I could really enjoy the dives. On all my dives, I was accompanied by DMT Michi, who was always incredibly friendly and helpful. Unfortunately, due to personal reasons, I couldn't continue diving. They really moved heaven and earth to make it work. Despite a relatively full schedule, my dives were rescheduled several times, but in the end, it just wasn't enough. That was 100% my fault. During that time, I was recommended many great snorkeling spots, and I was able to see numerous turtles there. I can highly recommend the dive center, not least because of the fantastic beach with its beach club. Beautifully situated with delicious food and good drinks.
