We had the same problem with Nov 24-Dec 1. Kept trying and found that each individual night was available, groups of different nights were avaialable, but it would NOT let me book those 7 specific nights. I called and was told the same as I could see online. I explained that each individual night was available and he checked and agreed. He was able to contact another department, I can't remember the name, and have them override it. We are booked for exactly what we wanted. For some reason, Disney must be blocking out certain stretches. Maybe so they don't have rooms with a random "off" night in between longer stays? Not sure and the CM who helped me wasn't either. Said he didn't understand it because I was just booking rack rate, no promotions which could definitely affect it. So, if you really would prefer standard view, check and see if each night is available. If so, call, explain, and have them escalate.
