I've already recommended you to my sister, who is visiting WDW in a few weeks.
Received alert that food had arrived at my hotel and it arrived ahead if schedule which was great. Got to hotel and our food was there!!
My one tip would be to BOOK EARLY. I started browsing 3 months out, but forgot to order until a week before our trip and there was only ONE delivery date left. We still got our stuff, but it was on day 3 of 8!
