Don't try getting change from the pursures office... go to the Casino cashier instead and ask for quarters (like you are going to play the slots...) They have plenty of change.
And as gdjoslin stated, if you plan on making use of the laundry, bring your own soap (travel size boxes or something) as the soap is very pricey if bought on the ship. Just be cautioned that the laundrymat can get crowded towards the end of the week AND if you are planning on ironing for formal night, do it EARLY!!!
