ticket upgrade at resort check in POFQ

[disneypk]

Has anyone done this? I need to upgrade my MYW 1 day base ticket. I need to add 2 more days and PH option. I know I can do this at guest relations, but if I tell the CM while checking in, will they let me pay them and add it on before they print my KTTW? Just hoping to save a stop at guest relations. I forgot to mention, my mom has 2 days PH from a previous trip so that's why I couldn't add my tickets when I booked the package bc everyone on the package has to do the same thing.

1) Front Desk CM's cannot sell/upgrade tickets.
2) You must go to
. . . Resort Concierge Desk
. . . Park Ticket Booths outside of the entrance
. . . Guest Service in parks or at DTD

The Resort concierge is right across for the check-in counter and I have never had to wait in line. It is an extra stop, but I have always done it this way and have never had to wait in line, versus doing it at the parks when you are excited and anxious to get started. I don't think upgrading my tickets has ever been more then a few minutes as long as you know what you want to upgrade to ahead of time.
