Hi, I'm not Tyler.......but......
Every resort so far has laundry rooms. They are usually by the quiet pools.
Maybe Tyler can give you an exact location.
Pop Century will have laundry facilites! They are cleverly located at each pool. The in the 50's, they are located by the Bowling Pin pool, in the Shoe Slots. In the 60's, they're located at Petal's Pool Bar. And in the 80's/90's, they're located in the Computer CPU.
Just switched my rezzies from All Star Sports to Pop Century -- I liked the review you gave the other day - will check in Dec 15 and hope to get to say "Hi"
