Does it really work with multiple kids? I live with multiple kids in a somewhat spacious (for a city!) apartment, and man, it drives me and the spouse crazy when the kids are staying indoors for the entire day, not to mention multiple days on end, for whatever reason (terrible weather, covid quarantines, etc.). I just can't imagine what it would be like doing an ocean passage with them on a boat.
(I spent a lot of my holidays as a kid sailing with my parents, but that was maybe a bit different as I was the only kid)
