Whenever I hear of someone going to disney, I encourage them to use garden grocer.
We ordered our groceries a few weeks before our trip and they were there waiting for us when we arrived to our resort. The process was vey easy and it was much cheaper than eating snacks/meals at the resort every day.
Friendly and efficient. Made my trip to the Orlando area easier knowing that my order was waiting for me when I got there. Saved me money not having to get a rental car to shop and paying higher prices at the amusement parks. I would highly recommend it.
