We are going to Disney in December 2016 and will be staying over Xmas. I have never used DVC before but I am thinking it might be a good option for our family of 4. We will have 2 teenagers when we travel who won't share a bed. What would our chances be of getting DVC accommodation at this time? And is there a time limit on how many nights you can rent? We would be looking at 14 nights. Appreciate any information or advice - thanks.
