I have wiped them out and reused the little bowls for popcorn. I bring a few Handy containers with lids for storage and for eating cereal. People here have said that you can get new supplies from housekeeping. We haven't done that. When we stayed at OKW & VWL in a studio, we had a lot more than the allotted 4 each of the paper products. This past visit at BWV, there were exactly 4 of each.
The coffee that's given is enough for the 10 - 12 cup coffee maker.
