We have three contracts with all different use years. My guide thought I was nuts, but I told him that I could keep track of it. I like the fact that my use years are spreadout, March, September and October. Since our family mainly travels to WDW for Thanksgiving/New Years, the Sep and Oct works great. Just in case that we need a little "spring break" or taking other peoples little ones during the summer, the March contract works great to cover.
