Great two days diving with the team , all the instructors are so nice and make you feel so relaxed . Not over sold at all which so many other boats looked like and the one on one training was next level Thanks to Joe for a great experience and epic memories
Andrea, Liv, and Lydia were all fantastic! They kept us safe, listened to our feedback/questions, and made sure we knew what we were doing. It was our first time diving and it was such a pleasure to complete our open water cert with them. I can't say you'll be as lucky as us, but we were even able to see a whale shark on our last dive! They keep the classes small, have multiple boats, and make the whole process so enjoyable. I'd absolutely recommend them to others who are learning to dive!
We had the greatest time in Goodtime with wonderful instructors. Big thanks to Lydia, Andrea and Liv for giving us the best experience throughout the open water course! We learnt all we need to feel safe while enjoying diving (we even ended up diving with a whale shark on our last day). I could not recommend it more!
Fantastic 3 days to pass our open water diver certification! The instructors and DMTs are fabulous and always helpful, put you in confidence to attend your dive! Cheers and thank you so much to Lydia, Andrea and Liv (Liv x 2, Liv x5748392)
We were debating between multiple shops for our open water course and we are SO GLAD we picked GOODTIME! We felt safe the entire time and learned so much! It was just the 2 of us with an instructor as they keep small group sizes which we prefer. They have their own dive boat, this is a huge plus as other companies in the area will share a big boat and it seems more crowded. The people are the best part, feels more like a community and everyone was so kind. We had the pleasure of learning from Max & Tim! Ana, Charly, Gary and Logan also helped and made our experience even better! 10/10 would recommend! Might stay and continue our adventure license with them 🤙
I want to say a huuuuge thank you to the goodtime team for helping us have the best time in Koh Tao. They really made sure we were comfortable and happy and went out of their way to ensure we got the most out of our time and money. I want to say an even bigger thank you to Shai who was my diving instructor. He adopted me for my open water course, my advanced and even introduced me to the nitrox course which I'm glad I got to do. Shai has taught me so much about the world of diving and I feel like I've come back with priceless knowledge and understanding of the ocean and how to keep myself safe. I'm so grateful to have spent my week in Koh Tao with goodtime, I've had a smile on my face since my first dive. I will definitely be back in the future for more diving. Wishing you all the best 🥰
