We had breakfast & bed time snack items delivered & that have us more time in the parks because we we're able to quickly get ready to leave in the morning & if we needed something before bed it was available without having to scout it out.
Worked really well for our Disney vacation. The delivery was at our resort when we arrived, refrigerated items were in the Disney refrigerators. We ordered mostly breakfast stuff, snacks, fresh fruit and cases of water.
Having breakfast in the room with small children is a major convenience!
