Amazing experience

The dive team leader was well organised. Each dive was briefed to ensure a safe and informed dive. Everything from currents, marine life, dive times, drop off and pick up and more helped ensure each dive was as good as it could be. The food cooked by on board chef was excellent. The aft of the boat was organised well and each dive team supported with an experienced dive leader. My wife unfortunately had a medical issue, but the dive leader (Golf) went way above what we expected to make sure nothing was left to chance. We felt very cared for throughout the whole experience. We would highly recommend Sea World 1.
