I don't know what you could do better!
My friend suggested I do this before we left for Disney. We arrived at 1am. Out groceries arrived earleier and as we were checking in, we were able to bring our groceries to our room. It was wonderful! Did not have to waste time shopping. Went straight to the parks the next few days. Even deliver cases or water and sunblock!
Garden Grocer is a total must when visiting Disney. Also, there was a slight mix up with the name in my order at our resort, and when I called Garden Grocer they took care of it in no time. Thank you!
