I can't speak for what the bus situation looked like at AoA, but this past weekend we took the Skyliner to EPCOT and it ended up taking us an hour and a half to get there. We had to wait in a line about 20 minutes at AoA, while anyone from Pop was able to get right on (they said because Pop didn't have a bus they got preference, so continually loaded from that side and only let AoA on when there was a break). Then, we had to wait in a ridiculous line at CBR, only for the Skyliner to EPCOT to go down after we'd waited about 30 minutes. Finally got out of that line and hopped in the (non-existent) Hollywood Studios line and walked to EPCOT. Next time, we would just take the bus and save all the hassle - even if we had to wait for an hour to get it.
