I was at Goodtime for the last week of march 2026, as I know Lukas already from my time on Koh Phangan. First day he was busy, so I was diving with Edu, who was a nice guy guided me nice and slow as I like it. The next day´s I was diving with Lukas and it was as expected. He´s a really good instructor and guide, I really can reccomend him, his professionalism is absolutly great. We had some very nice cavern and wreck dives.
A fantastic dive center with excellent organization. Our group of five did the Basic Dive and were accompanied by two very friendly and competent instructors, Lydia and Ana.
An absolutely fantastic experience with Goodtime Adventures Scuba Diving. A super friendly team, professional service, and a relaxed atmosphere. You feel safe and well looked after at all times. I can highly recommend them. Ask for Lydia or Ana as instructors when you arrive, and with a bit of luck, you might even get Mike, who can accompany you as a photographer with high-end equipment and capture your dive in incredibly beautiful pictures—all in all, 5 stars!
The introduction to the diving course was excellent; my nervousness disappeared immediately. Lydia, as the diving instructor, is very competent. I had a lot of fun. Great job, and I would definitely do another dive at this diving school anytime.
It was a fantastic diving experience. The instructors, Anna and Lydia, were sensational, and I felt safe and well looked after at all times. Everything was explained simply and perfectly. I can absolutely recommend it.
Another incredibly amazing experience! It was my fourth dive. Since it's been a while since my last dive, I was grateful for the excellent instruction here. Highly recommended! A huge thank you to our dive instructor, Lydia – thanks for having us! Hope to see you again soon!
