its tough, and I was actually looking at end of schedule in mid Oct a week ago. There are definitely competitors out there but seems like someone cancelled a Tue night and Thur night in Sept. I plan to use a BOGO either before or after those free nights and see how many nights I can string together. At some point, it may make more sense to book through a consolidator (Costco travel, apple vacations, pleasant holidays, etc) for a package deal.
