We completed half the open water diver course in the UK and finished the rest of the course with big blue. Big blue were completely accommodating about this and we had a private group to ourselves, which was obviously good because we almost had 1:1 instruction. The only downside to this was that it made it more difficult to meet other divers, but the dorm bedrooms and large social area meant this wasn't much of a disadvantage. We absolutely loved diving with big blue, our instructor was very very knowledgeable but we could also have a laugh with him. Went to some fab dive sites and even saw a turtle! Definitely one of the best weeks of our trip and would 100% recommend big blue to anyone!
