Hey Sarah, My advice would be to book as soon as you are reasonably able. I went down to PDC for a scouting trip two weeks ago and thought I was doing it with so much time left for my preferred Nov 2011 date. Turns out when I checked on availability with their WC, the middle two weeks for Nov 2011 had already been booked! Luckily I wanted the 5th anyway but still-- crazy!
