The staff at Big Blue definitely made my Open Water course much better than I could've imagined. Each one of them is so knowledgable and so much fun. I was lucky enough to meet most of them, but you won't be disappointed with either one as your instructor. I even went on to do the Advanced course, which I wasn't planning on at all, because I had such a great time in the Open Water course. The reason I didn't give 5 stars is only because of the free accommodation with the course, it's free for a reason. Do yourself a favour and pay the extra money for a room. That being said, the accommodation has nothing to do with the diving at Big Blue which is the reason why you'd be there in the first place. Eventually I want to do my Divemasters and there's no other place I will do it other than Big Blue!!
