I would have went and ask about it at the front desk.In October our neighbors were staying on rented points their magic bands did not open laundry room door. For those talking about paying for machines, there are no coin or card machines in the member laundries.
Makes a 1 bedroom or 2 bedroom unit look a lot more attractive.
A followup on my original post.
We stayed at CCV Dec 9-12. Our reservation was a "hotel"-like "cash" reservation directly with Disney, as we are not DVC owners.
Our magic bands opened the locked door to the CCV laundry room [it is on the 4th floor, off a hallway overlooking the lobby area] and we were able to do laundry with no problem. FWIW, we did laundry a couple times during our stay, and other than the first time we went to laundry room to locate where it was, we never saw anyone else in there.

The only DVC resort that I know of that really restricts a non member from using the free DVC laundry is Aulani. They do not have a separate laundry room for DVC members so the front desk provides tokens so you do not have to pay. And they do check your KTTW card to see if it shows DVC member.
I heard others say that the CMs at VGC also are pretty strict and they too use tokens.
