Are you staying on site? If so, I've used the laundry rooms at POP and one of the moderates and didn't have a problem with crowding...not in the summer or super busy time, but there seemed to be enough washers/dryers to accommodate those times as well. Seems more convenient than going off site. Just bring your room key to get in and I bring my own trial sizes of detergent, Bounce, etc., and LOTS of quarters.
