If all ressies are taken online, getting CC#s would be fluid; most people would register and have the info already in the system. Disney could also term most of the CMs at the call centers, saving that much per year on salaries and streamline the entire ADR system. As it stands now, we cannot print off our ADR lists - you have to wait until you get to WDW. You can't even call and cancel a double-booking without fear of a CM accidentally canceling the wrong one. This is my current situation: I have two restaurants booked at the same time. I do not want one of them and would very much like to cancel, but I've had problems in the past where they scratched the wrong one, or changed the time, or did something a laboratory monkey wouldn't think to do.
Whatever this new system is, I welcome it. If it allows for online booking, I would gladly give my CC#. 90 days out is no problem either, so long as it is the same for everyone across the board. I don't want to hear about certain people (i.e. staying at deluxe resorts or other) getting additional time.
