⭐⭐⭐⭐⭐ Did my Advanced Open Water with Good Time Adventures and had an incredible experience. My instructor Fabio was great. He really made sure I understood everything with the exact mix of theory and practice, helped me improve my skills and feel more confident in the water. The night dive was something I was nervous about, but he made me feel safe and it’s an experience I’ll never forget. The boat crew was lovely too, instructors Ana and Shai and the other students made the whole thing even more fun. Highly recommend! 🤿❤️

Doing the open water diver at good time was an amazing experience. Our teacher Lydia really took her time to explain everything calmly and understandably, it was perfect to get into the world of diving. She also focused on our weaknesses, so we could improve a lot over the 3 day course. I can 100% recommend doing your open water diving course with goodtimes and lydia!!
