I would play around with the Disney world site putting in dates and seeing what dates come up and I would book them even if only 4 days come up in the time fame you want...Like December 28-29-30-31... I would add more dates as they come up or open up...until I get the dates that I want, I have done that with resort rooms and it does works...you may have to pay for 1 night on a few of them before you get the all connected. After you get them all you just call and have them put them all together.
