We stayed in the cabins at Fort Wilderness and wanted some essentials, breakfast supplies and a case of bottled water in our cabin. The groceries were brought to our cabin and put away-- couldn't be more convenient! Also was a great money saver for us. You can bring bottles of water to the parks with you, which we did every day.
Saved alot of money by purchasing a case of water instead of having to buy one bottle at a time in the parks at $2.50ea. I also bought apples, oranges and cut up fresh fresh that was refreshing and nice to snack on while in the parks.
I would definitely use Garden Grocer again on our next trip to Disney. It was well worth the delivery charge and the prices were reasonable.
