I am not doing the online checkin because I have a location request, as well as the accessible room request - but I am staying at CSR which is HUGE, so location really matters! This is my honeymoon, so i want to be AWAY from the pool/arcade/etc but also on the side with the first bus stops (need it for a powerchair)... I want to be able to talk to them there about such things...
I am also faxing my request ahead of time and calling the hotel a couple days before to make sure everything is set!
