What happened to Tusker Dinner?

[SB in KY]

Have made all of our ADRs for our trip right after New Years. Got everything we wanted except Tusker. The latest Dessie available any day we are there is 1:55. They still list dinner and tons of times are open for breakfast and lunch on all our possible dates so I am pretty sure dinner is not already booked up. I am guessing for some reason they have not opened dinner Dessie's for January yet?? Anyone know what's up?

Maybe it's because the park closes so early in January? /total guess
