Most likely yes.
All regular US mail goes directly to the resort.
So a US mail carrier can get a letter or package with just a house #, street name and zip code to the right place. It may take the US Post Office a day to find the time to look up the zip code for the correct town & state.
For UPS and FedEx all packages go to a WDW distribution center and then shipped by WDW to the resort.
Again I would think the WDW distribution center would recognize the address of the resort.
But since POFQ and POR are right next to each other....when you arrive at POR, if the package is not there - ask the front desk to call POFQ and see if they received the package.
POFQ = 2201 Orleans Dr. Lake Buena Vista, FL 32830.
POR = 1251 Riverside Drive, PO Box 10000, Lake Buena Vista, FL 32830.
I would think WDW package distribution would recognize
Riverside Drive as
Port Orleans Riverside
