Everything I'm seeing online is saying that generally people are naked or only covered with a towel in saunas in Sweden. Is this also the case in hotel saunas, or only in public ones? I'm hoping to avoid bringing a bathing suit unless absolutely necessary, and I'm guessing I won't need or be allowed to wear one for most saunas. Is my reasoning correct?
Also, if anyone can comment on the same question for Norway and Denmark, I'd be grateful.
