I am getting the PAP, however, I'm not picking it up until the day after I arrive. How do I get discounts on restaurants at Citiwalk (the day I arrive), if I don't actually have the PAP yet?
Um, I think you need an activated PAP in order to get the discount at a restaurant/retail shop. (you might get a discount on your room - but you'll have to show the PAP at some point during your stay I think)
You can't get the AP discount at Citywalk without your AP. If you are in Citywalk, why don't you just walk over to either park and get your AP? It's only a few minutes away.
Sure, just go to Vacation Services at either park and they will take your picture and print off your AP. Then you can leave the park and go to CityWalk.
