Online check in just means everything is ready for you- room cards are printed, your welcome packet and parking slip is ready, etc. It doesn't really affect your accessible room. Since you still have to check in with a CM, then if there are any issues with room location, it could still be discussed. I've stayed at CSR several times and as it is so spread out, and as there ARE roll in shower rooms way back in Ranchos, I would request another building now also, esp. before I got there, like KPeveler. I'm doing online check in for my DVC stay at AKV in September and am not expecting a problem---Kathy
