You will have to use your imagination.

My friend just told me she found Sex On The Bedskirt in her room at a reputable hotel. She did the right thing and called housekeeping. Management did the right thing by asking if she would like to move to another room. It being late at night she chose not to. Housekeeping replaced the bedskirt with a brand new one.

Situations like this one are why I recommend wearing slippers in your hotel room because you never know when you will have to walk across a bedskirt. Pooh pooh me if you like, but if carpets could talk ... My friend was too traumatized to check the mattress. I believe you are better off knowing.
