Might be a new "winter" AAA promo that hasn't been announced yet (speculating). If it's cancellable as usual, I'd book it, and print out the res showing the inc. free bfast in case I need to show it at check-in to press my case. Then, check later to see if a new promo gets announced, or if there's a better rate. Worse case, you've got the printout you can show to the FD and insist on rate benefits. But I bet there'll be a new AAA promo by then, anyway...like Trustguy says, it's a nice frequent promo throughout the year. I use it most stays, too, and I've probably even booked it when there wasn't a new promo showing, yet, too.

There was one period awhile back when I think they changed the code from BREAKF to something else...but don't recall exactly.
