Thanks for your feedback and we're really sorry you were disappointed with the initial briefing and the length of the instruction. Our local teams are contactable before and during your cruise to try and make the experience as enjoyable and stress-free as possible so it’s disappointing to know you didn’t have the relaxing experience you, and we, would have wanted. If we can be of any further help at all, please feel free to contact our team at customerservice@leboat.com
