My one tip would be to BOOK EARLY. I started browsing 3 months out, but forgot to order until a week before our trip and there was only ONE delivery date left. We still got our stuff, but it was on day 3 of 8!
Excellent service. GG had my food delivered to my resort without problem. Could not have been an easier process and they are fantastic with communication.
I received a text during my flight confirming delivery to my room and a follow up telephone call while at the airport. Our groceries were delivered to our room before we arrived, so we could immediately begin enjoying Disneyworld. The service was excellent.
