I just did the online check in for an upcoming trip in October. I was able to request a section of buildings (Pop), but nothing more specific. I don't remember being able to input my arrival time (11:45 at MCO). Can that be modified? Or is it not a big deal since I will probably arrive on property, I suspect around 1:00ish. I'm still debating whether to hit a park or have a resort/Disney Springs day.
