I refuse to pay rack rate for any WDW resort. Unless there is some kind of discount, I don't go!!! I have stayed at the Polynesian but that was with a great discount. Stayed at the CR, in the North Wing way back when, but again, got a good discounted rate.
There are plenty of people that don't know any better and book rack rate rooms. I have actually had one person tell me that they always book at the full price because they are afraid something will happen if they try a discounted rate...like find no room for them when they get there, or get an alley view room. Also that they 'think' they are going to get better service if they pay full rates!!! Nothing I say can get them to change their minds.
So, yeah, these rooms are expensive if paying rack for them. And Disney knows full well that there are people out there that will pay it!!!
