As lougord99 has noted, Choice won't allow any member, including its highest level Diamond elites, to book more than 100 days out--in other words, as of the time of my post, for dates roughly July 1 and after. Lower status levels get even shorter windows for booking with those without status limited to 30 days from date of inquiry.

To solve your initial problem, look for availability for the moment no later than mid-April. Be aware, however, that many Choice properties vary the points needed for a redemption every several months. Thus, the points you can currently see that are needed may not be the same as the points needed for a redemption in the fall. In addition, the new FlexRewards program may impact the number of points required.

To extend your booking window for free, the Barclay Choice Visa is a no-fee card that confers Gold status (60-day booking window) and generally has a 24-40K sign up bonus: http://www.flyertalk.com/forum/choic...edit-card.html.
