I am going to book a Bernard's Tour to Orient Beach in a few weeks, I see that it's clothing optional. My 2 girls (16 & 20 years old) don't seem to like the fact there will be nude people. How bad is it really? I assume most will be clothed? I'd also assume many will just be topless? And is it big enough to likely find a place on the beach not quite as busy, thus having less naked people? Trying to get some info to ease their minds about it. Thanks!
