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!
Great service and easy to use! Our groceries were there before we checked in!
I'm always happy with Garden Grocer! I use it every time I travel to Disneyworld.
