I’m a DVC member and I always stay in a studio when I visit Aulani, WDW, or DL. During my recent visit to Aulani in December, I was told by the CM at guest services that I could get tokens from guest services every day for the laundry. I didn’t need to, but it was nice to know it was an option. I’ve never had to pay to use the guest laundry while staying in a studio and I always stay on points. Just remember to ask the front desk what the procedure for using the laundry is. I know the Grand Cal gives you a laundry card to use but you have to get it from the front desk. It’s been a while since I’ve done laundry at WDW, but at BLT I just remember going in the laundry room and using the machines. I don’t remember having to pay.
DCL is the only place I’ve paid to do laundry.
