I would definitely recommend Garden Grocer to anyone I know going to Walt Disney World. I was so pleased with the service before and after our order was delivered. When I ended to make a product substitution, that was taken care of very quickly. Before we arrived at our resort, I was notified that our order had been delivered and was waiting at Bell Services.
I wrote a brief review of Garden Grocer here: http://www.lovelogicandlaughter.com/2014/06/disney-tips-and-tricks-disney-world.html
Very Pleased with the service and will do it again. Way to stock the mini-bar on a hectic Disney Trip.
