Having dove in many places around the world, I can attest that Cozumel is one of my top favs. We usually go in Feb/Mar and the water is clear and temperature around 80/81F. Deep Blue is the company that I have stuck with and love them.
I can confirm that the visibility is usually a bit better than that in the waters around Cozumel. Glad y'all did a night dive -- a lot of people are hesitant, but the night dives in Cozumel are always awesome!
Hey. We didn't really want to promote them. It was barefoot divers. The instructor was really good just the shop was weird. The price was 110dollars for 2 day dives and I think 50 for the night dive. Enjoy🙌
