highly professional staff that clearly knew what they were doing. A bunch of us came ready for our certification dives, and Princess clearly walked us through the process and kindly answered our many questions. Manu was our main guy the first day, and we had a blast. Visibility was crap both days we dove (in June), so make sure to find out which sites you will be diving in beforehand and check with them. The boat was very clean, and the staff was great with our group. Definitely recommend these guys if you are on Phi Phi, and the prices are the same EVERYWHERE on the island so don't waste your time price matching. Cost was about $5700 Baht for our four certification dives and our PADI Pic Cards. I believe it's around 7,000 Baht to get a full certification with the classroom training.
