All DVC Rooms should have a full size (10-12) cup Mr Coffee style of brewer. There have been some reports of studios occasionally having a 4 cup brewer. If you are in studio and there is a 4-cup brewer, Housekeeping will bring a full size one on request.
If you are there on points, you'll need to bring filters and coffee. You'll only get one, maybe two, prefiltered pouches of coffee each service day (every four days). If you are staying on cash through DRC, you'll get service every day.
