We used them last year and it was so worth it. They brought us everything from milk, soda, orange juice, bacon, eggs, frozen pizza and dry goods. I picked a two hour window for delivery. I arranged this based on the fact that I knew we were getting up early and would probably hit the MK as soon as we got there and would be ready for a late afternoon break. Not to mention that I would know my room assignment by then. I had left my cell number and they called to find our room. Shortly after, they delivered our groceries. After hauling everything up three floors (there were 6 adults staying at OKW and we planned on starting off with breakfast at "home" every morning) and unpacking everything (including putting it away in the kitchen); he definitely deserved a tip!!! We gave him 10% of our bill.
