Well, since you are a DVC member, you would not be kicked off, I wouldn't think.
It is just we peons that would suffer.
I don't think it would be TOO much of an issue, but definitely an inconvenience. We just need to know about it sooner rather than later. We have to put in for our vacation days November 1st for the following year, and once the vacations are requested, they are locked in.
I've seen that the January 2013 DVC cruise did not sell real well, so I am not sure if that will affect the decision of whether or not to have and when to have the 2013 fall sailing.
