I was really pleased with my Garden Grocer experience - our order was waiting for us when we checked in to our resort, and we saved a ton of money by having our own snacks and drinks with us each day in the parks. I'm already recommending to friends who are heading to Orlando in 2014!
Garden Grocers was a complete time saver! We were visiting WDW for only three days and wanted to spend as much time in the parks as we could. We placed our order the week before we left and it was ready and waiting for us when we arrived at our hotel. There was no need for us to take a trip to the grocery store to stock up on essentials. It was easy and very reasonably priced. I highly recommend using Garden Grocer.
Definitely a quality service based on our experience (notes from Canadian customer).
