Before I start -- let me be clear I am not trying to cheat the system here, so if any of this is not legit, please let me know. 
I am planning a few trips to WDW next year, and will be purchasing an AP. (I am NOT a FL resident.) On one of those trips, I would like to take my cousins along -- they are 13 and 14, and are life-long FL residents.
My question is, how can I go about purchasing resident tickets for them? Obviously the ID I produce will not be an instate resident; will Disney accept my word that they are , at the GR window? (I would expect not, but who knows?) Can I have photocopies of the kids' passports with me? Or would their parents (with their FL IDs) need to purchase the 3-day play passes ahead of time?
Also, a follow-up question... while researching this question, I read somewhere that one can upgrade package tickets to FL Resident passes. So if we go free dining, and get two-day tickets with our package, those could be upgraded to the play pass?
Still trying to work out the details but I'd like to know this before I approach my aunt with my grand plan.
TIA for any help!
