I have never done online check in...never really considered it, really, because I like to speak with the person at the desk in case I don't like the room assigned and want to ask for a switch. I also like any additional info they may give me at that time. I notice that most people on the DIS seem to use online check in and I'm wondering if there is some great advantage I am unaware of! I realize it is a shorter line but is there any other advantage? Am I the only one still doing it the old fashioned way?! I'll be staying at the Poly, if that makes any difference!
