Annual Pass Universal

AP Holders…I’m getting 1 AP per room for the hotel savings at HRH. I have seen various sources that say you can pick these up at the Universal kiosk area in the hotel lobby, thereby saving yourself time getting to/from the park day of check-in. Are these stations manned? Should I order online and just print them at a kiosk? I realize they won’t be “activated” until I enter the park. How about buying extra tickets with the AP discount? Can that be done in the hotel? Do I have to get extra tickets at the park? Do I have to enter the park first to “activate” them? Thanks.
