I think January is about the same demand level as September. So to give you an idea, right now you can get GVs at both Jambo and Kidani in September (at least for 9/20-9/25 which is what I asked about), and that's at the 7 month mark.
I think you should be just fine at the 11 month mark, but of course call the first day just to be safe!
Good luck!!
