I'm sure this has been discussed before... but bringing it up again for convenience.
For those that have stayed at either POP or AoA - do you use Skyliner or buses for transportation to DHS and Epcot? If Skyliner, how early do you recommend getting to the station if you want to be there for park opening? Also - how early do buses start running? I have heard "45 minutes prior to park opening" but is that set in stone? I know that most parks open up 30 minutes prior to scheduled opening, so does that mean that the buses open 45 minutes prior to that, or 45 minutes prior to scheduled opening? (i.e. if Magic Kingdom has a 9am scheduled opening, but they let visitors in at 8:30am, do buses not start running at resorts until 8:15, or is it 7:45?)
