I am doing this too when we go in October. The last time we did a Disney trip we used
Amazon Prime now. Are you an amazon prime member? If not, sign up for a free 30 day membership trial close to your trip. You go to the site, choose the items that you want, then choose a two hour delivery window when a driver will deliver everything to the lobby of your resort. The prices were the SAME as if I was shopping at my local grocery store back home. Shipping and delivery was free. You will enter the name and address of your resort and you are good to go. We entered our order before we got on the plane, signed up for delivery that night between 6-8 pm and loved it. They even packaged our cold items in nice cold bags with a foil lining. If you need more stuff during your trip, you can get it within two hours of placing the order. It saves TONS of money. Just have someone in the lobby to greet the delivery person, they do not deliver to your room, just the lobby. We tipped the driver! Happy planning!
