Where to pick up and upgrade tickets

[kokomos]

What are my options? I'm getting a season pass and possibly upgrading my sons 2+2 to a season pass also. so I have a few questions 1- do I need to upgrade his before he uses it or could we wait until day 2? 2- I would like pick up my season pass the afternoon before using ( staying offsite) what time do ticket offices close? Can the be picked up and upgraded at any resort? I don't want to pass for parking just to pick up tickets so im thinking parking garage at if ticket office is still open?
