We are staying in a studio (split stay Kidani and SSR) but we are going for an almost 2 week vacation so laundry will need to be accomplished. How convenient is it to use the laundry facilities at the pools? Are they usually packed so you have to do laundry off hours or is is reasonable to expect at least one machine to be available in the early/mid-afternoon when we might be taking an afternoon pool break? Also do I need to bring quarters for the machines?
