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!
Garden Grocer was simple to use. It also allowed our family to have a quick and inexpensive breakfast and get out to the parks each day.
Fantastic! Groceries were in our room and in refrig and freezer
