I’m currently staying at the Courtyard Marriott in Gettysburg, Pennsylvania, and I’m very happy to have just learned that their guest laundry service is free!
Most hotels offer access to a washer and drying, but most, including other Courtyard Marriott locations I’ve stayed in, charge $1 in quarters for each cycle.
Unfortunately, when I was staying in the Courtyard Marriott in Stoughton, MA, my quarters got stuck in the top dryer. (Note to self!)
