I don't know if they have discounts for the time of day in January. the best time to play would be 10 am in Jan while in the summer it would be the worse. Also it gets dark around 5:30 in January so you would have to get out there before 3 I would think for 18 holes unless you are trying to set some kind of record for time. The weather for golf is great in Jan. I see you are from the North West so you should really enjoy golfing in the winter in Florida.
