We used Garden Grocer when we stayed at the polynesian in WDW for a week. The website was super easy to use and the service was prompt! Our order was at the bell station when we arrived. We ordered breakfast items and snacks which made it easy for us to get up and out to the parks early. Definitely would recommend Garden Grocer to anyone who is staying in Disney and not renting a car.
Convenient, quick service, responsive! Plus you save $, what's not to love?! Will use again and refer friends!
