To prevent decompression sickness, please do not take a plane within 18 hours after diving (No restrictions for snorkelling). Kindly check your return flight time as well.
If the original dive site's sea conditions are not good enough before departure, it will be replaced by a dive site with better sea conditions based on the instructor's judgment.
Those aged 51 to 59 must present a physician's certificate showing the participant's suitability for snorkelling.
