I admit that I am one of those SSR owners who always stays at other resorts. Anyway, I just called in to MS to change my December 20-25 reservation to another resort. As I've been warned, this is a very popular time for DVC members to vacation. There are currently no studios available at BCV, BWV, or WLV. They had plenty of one bedrooms available but I don't want to burn the extra points. I put myself on the waitlist and will see what happens. Does anyone here have past experience with a December waitlist? Did you eventually have your waitlist come through? I guess if worse comes to worse, I'll use my original reservation at SSR. At least I'll be in Disney World during the Holidays.
