For our recent trip we priced out Garden Grocer,
Amazon Prime Now, Amazon Prime Pantry, and Instacart. Instacart was almost always the most expensive for the items we wanted, so we dropped them from consideration.
Because of a combo of avilability and price, we placed an amazon prime pantry order, a garden grocer order, and three amazon prime now orders [one was a late night urgent luggage lock order due to luggage technical failure].
With Amazon Prime Now, I had placed the items we wanted into my prime now cart months in advance, and then checked in on them from time to time. Items dropped in and out of availability, so we were prepared for that possibility and identified alternatives, or in three cases, chose to order items as an add-on to our Garden Grocer order as we felt that had a better chance of being in stock, if more $. Note that you can only add items to your cart, there is no "favourite" or "wishlist" type option. We made a list of everything we wanted, so when an item dropped off but became available again we would remember it. THIS WAS VERY IMPORTANT TO HAVE DONE as we woudl have forgotten a couple things without this list.
For amazone prime now, I put in the delivery instructions to deliver to hotel bell services and to contact us if required, we would be available to meet them. We were not contacted and the items were delivered to bell services. With the app I could track where the order was once it was out for delivery, so we headed down and were able to pick up the order from bell services soon after delivery for two of our orders.
WDW did not charge us a fee for amazon prime now or garden grocer. There was a $5 fee for our amazon prime pantry order, which we expected -- they added it automatically to our room charges as the order arrived a few days before we did.
For all of the Amaozn orders, i added the address info to my address book ahead of the trip, of the form:
Firstname Lastname (Guest arr ## Mon)
street address of resort
Disney's Hotel Name Resort
Lake Buena Vista, FL, zipcode
address/zipcode info I took from the resort hotel's Disney website.
note I did NOT put the reservation # -- that is a valuable number that is not needed and is a potential privacy and other issue problem.
