It seems to me that swimming pools bring out a person's inner child to some
degree (perhaps due to the relative weightlessness?) thereby leading to
Kalus Rosh more so than, say, a formal dinner (even where alcohol is
served). IOW, even if the visual aspects of Tzenius were totally absent
there still might be an issue.
