I highly recommend using Garden Grocer for all your grocery needs for your Disney stay! It was so helpful having snacks and bottled water on hand as well as dairy products that we couldn't have traveled with.
I did my order on line from UK. When I arrived at my hotel my groceries had been delivered the exact time that they said they would be. I phoned my hotel a few days before my groceries were due to arrive and they kept them in storage and delivered them to my suite after I was checked in.
This is the first time I have ordered food goods for our hotel at Disney. Everything was exactly what we ordered and delivered within the time frame they said they would deliver. I plan to use them again.
