I am not sure what the current policy is, but I have never had any luck with the resorts doing anything AP related correctly. I would just save yourself the frustration and do it at the parks or guest services at Disney Springs.
I’m fairly certain you have to go to the Customer Service area at one of the parks, or the one at DS. We tried to have it done at the resort and they informed us they weren’t able to do that. You can get your AP ID card there, however I’m not sure if they give them anymore. Everything seems to go back to your MDE account. I looked up our AP tickets yesterday to see when they expire, and we had a huge barcode under our names. I assume this is for scanning when making a purchase that qualifies for the AP discount.
