Generally their hours during non-summer non-special events months are about the same, so it should be similar to what it is now. Right now it is 9 to 5:30, so I would expect most of January will be the same.
One possible difference - if there are any special events on the weekends generally they stay open later. They seem to have been changing their special events around over the past few years so I am not sure if they will have any during January.
The special events I am thinking of specifically are Praise Wave, Just For Kids, and Bands Brew BBQ.
