I think this is how it works, yes. It's the first time we've done it. We are just trying to wrap our minds around not having AP's!
We are buying the tickets online, printing them at home, and then we are supposed to be able to go to a ticket booth and exchange them for a hard plastic pass. I hope it all goes smoothly! I am also hopeful we can go the evening before and have it not eat up a day. We just don't want to hold people up in line the first morning we enter!
