I suppose you want redemption ?
I booked (April) from their webpage and there seems to be availability for December as well for normal booking.
The opening day has been delayed 2-3 times (from Oct to Nov, now Dec) but this is the 1st time they allowed booking.
By the way, I booked a fare "Le Meridien Break" the 1st day they opened booking (yes...I was watching like a hawk). I have absolutely no idea why, but it was dirt cheap (half off today's price)
