It all worked out great! We had scheduled our Disney trip at the resort, and after we arrived, our groceries were already there. Perfect timing!
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!
Very easy and convenient, will use Garden Grocer every time.
