Garden Grocer is an excellent service! They save us so much money while vacationing in Disney. I recommended it to numerous people while laying around the resort's pool.
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.
It was great for staying at Disney World! Food and snacks were there waiting on us when we got there and made the trip so much more relaxing!
