We've used Garden Grocer twice so far when we've gone to Disney World. Our grocery order has been at the resort before we even arrive from the airport. We love WDW however; in the long run and depending on the size of the grocery order Garden Grocer is cheaper than WDW. The variety of products is really nice too.
We will definitely use Garden Grocer again. I had forgotten to order one item and when I called the girl who took my order was so helpful and friendly. Our groceries were at our hotel when we arrived! Using this service saved us over $60 on water alone and we figured about $175 on breakfast foods!
This is the best idea if you re going to Disney, since all Resort Rooms have a refrigerator in them and will be a great idea for the breakfast items, , we took 17 family members to Disney for a week and it was great to have in the morning or a bottle of wine that was chilled for a late night cool down
