I wrote a brief review of Garden Grocer here: http://www.lovelogicandlaughter.com/2014/06/disney-tips-and-tricks-disney-world.html
Love this service.everything I needed was right there when I got tp the hotel.
We pre ordered our food to be delivered to our Disney resort and it arrived right on time. The produce was wonderful to have and it saved us a lot of hassle because we didn't have to bring breakfast foods with us in our luggage. I would highly recommend Garden Grocer.
