At CBR in December, the coffee packets were $1.14 each. I took Folgers singles and they worked fine BUT we did buy refillable mugs and ended up using those instead since the coffee makers are only 4-cuppers and there were four of us in the room. They don't charge for using the coffeemaker, only for the coffee, so we did make instant oatmeal and also brought cocoa packets (free with mug) back from OPR and enjoyed in the room.
