We've used Garden Grocer twice now. Very easy and convenient experience both times.
For a total cost of $150 by ordering from GardenGrocer.com my family of 4 had breakfast in our hotel every day of our 9 day stay. Also, this cost included snacks to bring with us to the parks each day, and some supplies like paperware, plasticwear, suncreen and wipes, too. We even had stuff left over! And best of all, it was delivered to our hotel in advance of our arrival, and delivered to our room by the hotel bellman (whom I tipped 5 or 10 dollars). This cost is so amazingly cheaper than if we had eaten breakfast at the hotel restaurant and/or in the parks. Will certainly be using GardenGrocer.com again for our next trip!
I wish I would have ordered earlier. I waited until I got to Disney World to place my order, and I wish I would have ordered earlier to have the groceries ready when I arrived. It was good to get some fresh fruit and vegetables and milk for the family. Good stuff!
