We've also done online check in every year since it has been offered. We experienced being met at the bus when staying at WL and when staying a mods, it was a smooth transaction. We have so far, (in our many years of going) never gotten a room request granted, and I don't think online check in makes a difference since people on this thread have experienced both getting their requests and not getting their requests. For me, it is convenient and when you get off an ME bus full of people, the online check in line is usually shorter. But if it isn't just jump in the regular line since they can pull your packet as well.
