They all do. I'm not sure where the refill stations at BWV are since we don't use the mugs, but I'm sure they have them. Someone will chime in and let us know.
You can refill the mugs at the bakery and pizza express window at BWV (I believe there is one other place, but can't remember where). It's not as convenient as the other hotels, because you have to wait on line for someone to fill it for you instead of just filling it yourself...in the am when you go to get your caffeine fix, you have a long line to wait on at the bakery as others are ordering breakfast sandwiches and such. The self serve areas in the other hotels are wonderful (OKW has the same type of service as BWV-Good's to Go and Gurgling Suitcase are staffed and you have to wait on line for a CM to refill your mug).

With a larger refrigerator than the hotel rooms, especially if you get a one bedroom or larger, getting a refillable mug isn't as convenient as just filling up the refrigerator.
Since becoming a DVC member we have never gotten the mugs and always had previously. As Deb & Bill had said, having a large refigerator and stocking it is much more convenient.
