Took my 10yr old daughter for her first dive and so glad we took the plunge with Goodtime and Lydia. Lydia was extremely caring, patient, clearly a pro, and fun!
Ana was an amazing dive instructor! I got recommended Good time dives by a mate and it was awesome. This dive company has small ratios. I got lucky and had a private dive. It has been a while since I dived so doing a refresher and a fun day hit the spot.will be back cheers team.
What an amazing diving school. From the moment you enter, you'll be greeted with smiles and good vibes 🤙 I did my AOW, Nitrox and Deep 40 Specialty with Goodtime Adventures, and my experience was amazing. Both my AOW instructor Lydia and my Nitrox and Deep instructor Ana were fantastic teachers. Both were super patient and extremely knowledgeable, and I always felt safe and absolutely taken care of throughout all my dives. Especially Ana challenged me a lot which I actually really enjoyed, since I learned a lot and became more confident in my skills and in understanding dive planning and execution. The rest of the team were also super friendly and also always there to help if I had any further questions. Goodtime Adventures also deserve bonus points for cooperating with the dog shelter Kohkohpups and rescuing dogs on the island ❤️🩹
Did a Scuba course, Very nice place, professional and friendly. Bart was nice, my instructor shai was great Very recommended!
Had a fantastic few days doing my Open Water Diving course with Goodtime Adventures, I can’t recommend them enough. My instructor, Fabio, made the whole learning process very easy to follow and very fun. The two dives on the final day to Laem Thian Caves and to Aow Leuk will be an experience I’ll never forget.
⭐⭐⭐⭐⭐ I did my Open Water and Advanced Open Water certifications with Goodtime Adventures and honestly it was a lifetime experience. A huge thank you to Chris for being such an amazing instructor throughout the whole journey. Super chill, patient and genuinely fun to dive with, while also being incredibly professional and reassuring underwater. You can really tell he cares about his students and wants everyone to feel confident and enjoy every moment. He made the whole experience feel relaxed, safe and unforgettable. The dives were amazing and the overall vibe with the team was great. Huge thanks as well to Lydia, Liv, Fabio, Anna and Mika for making the whole experience even better everyone was so friendly and welcoming from day one. Definitely recommend Goodtime and Chris if you’re thinking about doing your diving certifications in Koh Tao 🤿🌴
