i feel your pain, there will be a lot of people jumpin to the defense of the disney online system but i agree with you. it is like so much other online stuff is a good tool, but i call and talk to a nice cast member when i am ready to book or even if you have any real questions.
they can usually help you,
but another thought is to ask your question here, a lot of very smart disney people on this site with excellent pricing and other info.
