hmmm ... I just went to the mobile site and tried to book a trip beginning in late December, 2017 and rolling over into January, 2018 and it seems that the site is letting it happen. So maybe Disney's site is set up to allow booking into January, 2018 if the beginning of the trip is in December, 2017? If only they would release the entire year - I'm itching to get actual pricing for our February trip. Seriously itching.
