Island Princess Laundry: Quarters or $ bills??????

Going to Hawaii on Island Princess 11/7 sailing. Can someone tell me if the laundry uses quarters or dollar bills. It seems like it has been a 50/50 split on the other ships I've been on.

Thanks

Can tell you on the Diamond the machines take quarters but there is a machine in the room to make change. I would think it would be the same.

Hi,

Coin operated;; paper money changing machine on the wall.

To be safe, we always take a roll of quarters with us because many times the "bill changer' has been out of order.
