If you use the pick up laundry service, its extremely expensive. I want to say I paid something like $8 to have a pair of khaki pants washed. The GCH has the best of the three onsite laundry facilities( PP has no laundry and DLH has like two or three washers). It had something like 6 regular washers and one very large one and about 8 dryers (the large commerical type). I would think that there would have to be a laundry mat somewhere there on Harbor however. I did do laundry twice at GCH, it was crowded both times but we still managed to get it done okay. Oh and Blackjack Delta, I was also doing laundry for a crowd since it was my family of four and my brother's family (he did his along with me). Again, it was a challenge but at least they have more than just one or two washers/dryers like some hotels.
