You will get 1 maybe 2 packs in each unit that make about 4 cups. Bring Mr coffee type flat bottom filters and coffee or as Mrs. Milo, get the filter packs.
You'll either have a 4-6 cup or 10-12 cup Mr Coffee style coffee maker. If get the smaller and want the larger, just call Housekeeping and you should be able to request a larger one. The filter packs they provide on each service day make 4-6 cups of coffee.
The trick to asking for extras is to ask politely at the front desk. For example, we always get more laundry soap at the front desk and they don't charge for it, but if they bring it to your room, then they charge you.
At least that has been my experience, also sometimes if you see housekeeping and ask nicely they will give it to you for free.
DVC printed policy is that you pay for additional coffee and laundry detergent. As discussions of work arounds for stated Disney and DVC policies are not allowed on the DisBoards, this thread is now closed.
