From experience, I would not order anything at MCO’s Starbucks.
What you need to find is an actual Starbucks location. There is one at Disney Springs, that I did my free there last year.
Good or bad, I’m usually somewhere else besides home, around my birthday. There are more actual Starbucks at some places than other. I find in Florida, I tend to have a rental car, and always get my free Starbucks outside of Universal. But I’m glad the Starbucks in Universal do take my AP discount and my Starbucks app payment, so I at least get a cheaper price and Starbucks points.
