Dear Luzia,
We regret the details that were not completely satisfactory. Snorkel masks are included, sorry you didn't ask the crew. Regarding the beach stop time, we try to make it enough for everyone, but sometimes it is and sometimes it is not. About the ship's audios, starting next season, everything will be available in each language, in downloadable audio guides. We always try to improve, but we can't do everything at once. We hope there is another opportunity and everything is perfect. Thank you very much for your review and best regards
