We stayed at Disney's Wilderness Lodge. The process was so easy! When we arrived, our food was with Bell Services. They had kept the perishables refrigerated and they brought it up to our room after we checked in. It was especially useful since our children have food allergies.
This was our first time using Garden Grocer and it worked out perfectly! Our family (7 of us) were at Disney for 4 days, the groceries arrived hours before we did and they were brought to our room upon arrival. It was wonderful to have milk and fresh fruit for our stay - the prices were reasonable and the convenience can't be beat. We will use them again!
