Well, except the guide and the boat crew who where friendly the rest is a bad experience.
I planned two dives at Cozumel, during the first one I had an issue and I could not do the second dive.
They charged me a full price for the second dive arguing the I occupied a place on the boat which was almost empty...
When paying by credit card a commission of 4% is applied. No alternative accepted.
Probably one of the worst diving center experience around the world.
