I found this when I googled "Tampons Cruise Ship."
I was afraid to use a tampon until I was a sophomore in college, when my family went on a cruise over the Christmas holiday. My sister and I were sharing a cabin, and I told her I couldn't go swimming. When she found out why she gave me a fist-full of tampax and trapped me in the bathroom. I tried to get out but she leaned all her weight into her shoulder and kept the door pinned shut.
"Do it," she said.
At least that's how I remember it.
