The only thing I can tell you is my experience. I was in line, at Pop, about an hour after our flight got in. However, the line for checking in at Pop was incredibley long and slow....there were a ton of people checking in. And no, they didn't all get off the bus with me!! There were perhaps, about 8 others on the bus with me. I would give yourself about an hour and a quarter to get to Pop, then maybe another 30 mins to get checked in....be aware though, you may not be able to get into your room. You will be able to leave your bags with bell services though and then head off to the parks. Hope that helps.
