I think you'll be okay if you reserve at the 11month window (using the online booking at 8am Eastern time), unless you want a standard view. I have tried about a couple times for 2br std view at BLT during peak demand periods (Thanksgiving and NYE) and studio std view during f&w at 11 months and have not have any luck. Some folks recommend "walking the reservation" in cases where the room category is hard to get. It seems like a lot of work, but may be worth it if must have that category.
