By end date, do you mean when the BB offer will expire? They don't let us know that, and just have in the fine print that the offer can change/expire at any time.
I don't know how they will work this year, but it used to be that the room discount BBs would stop around the middle of August (when people arrived for their stays during the
Free Dining dates), and a new FD BB would start that allowed guests to book a FD package for the next years FD dates a year in advance.
Then in October that FD BB would expire and a new room discount BB would begin and that one would include dates into the next year.
And then all of the sudden last year they completely quit offering any BBs for quite a while, saying "we're not going to have BBs anymore" but finally started them up again.
Since they seem to be changing deals around this year, it's hard to say what they will do with BBs.
Recently, and still being reported as the current BB, the BB offer has been for:
40% off Deluxe Villas
40% off Deluxe
35% off Moderates
35% off Values
For stays most nights:
2/27–3/5, 5/8–5/27, 5/31–6/4, 8/21–10/8, 10/23–10/29, 11/13–11/19, 11/27–12/3 and 12/11–12/24/11
But this BB can change at any time, and can go to no BB at all being offered or a different BB offer can start. So always call extension 8844 from your resort room to inquire about BBs.
