On my 14 day Alaska cruise I would venture to say quite a few towels went unused 😉 . Who doesn't love a Cutback thread. It keeps the page count hits high for CC 🤣. You are right though, the logistics would not be good to go to towel hut only. I am just a bit sore from getting two different demand letters over the years via email to pay for pool towels from my room. I wouldn't dream of taking one of those mostly ratty beat up blue towels.
