I think it's great to be able to get your grocery delivered.
Used GardenGrocer for our Disney Orlando vacation. Easy ordering and great customer service. All products had long dates (unlike some grocers who use Internet orders to get rid of almost out-of-date stock) and great customer service. Not only keeping us in the loop regarding when and where the tems were delivered, but in our case reaching out to double-check we had not accidentally over ordered an item (again other grocers may have just filled the order without bothering to check) Overall am excellent experience!
Our food was waiting for us when we arrived at the hotel (Art of Animation) and our order was complete and packaged well. Website made selecting our groceries easy and it was nice to have a good selection in the room.
