I don't beleive so.
The package delivery soesn't deleiver the packages directly to your room (or cabin or tent/camper). All packages are dleiver to guest services at your resort, they send you a message (leave a message on your in room phone) to advise you that your package has arrived and you go to guest services to pick it up. They all need to be signed for.
It has been my experience that all packages are delivered to the Meadows Trading Post. They are to arrive there around 3 PM the following day.
I have used this service many times. I have never had a problem. Love it.
