Also realize that you will have to pick up the box from the convention center and pay $10ish for it. It will only be available during the 9-5 time period for the most part.
It has nothing to do with DVC- all the convention hotels have a service contract with a shipping company- they recieve and send all packages. Since the Contemporary resort has a convention center the shipping company will recieve your package and charge you $10 for doing so. If you look at pictures of the contemporary resort- there is a long building with room to pull up to it aound the coner from the main enterance. That is the convention center. Once you are at the hotel you can either walk across the parking/driveway area to the convention center outside or walk through a series of hallways (ask where it is and then you will start seeing signs as you get closer. It is a shorter walk outside but cooler and dryer(if raining) inside.
Again it has to do with the convention center contracts of the Contemporary- nothing to do with DVC. You would get the same thing happening at any of the other convention hotels (Grand Floridian, Corando Springs, Yacht Club I know for sure).
I was just giving you the information so you were prepared when you arrived. I know if I didn't know and arrived and had to pay the $10 I would be really ticked off.
