It was awesome to already have groceries and diapers at our hotel when we arrived!!
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.
All of my food was delivered to the resort on time! It made things so much easier on vacation!
