I wouldn't worry about it...after the holidays and before Prez Day it is very, very slow at Disney. MLK Jr weekend is a little busier, but probably one of the lightest holidays at Disney (we've been there...it's lighter crowds than Labor Day even.) MArathon weekends are busy for the hotels, but they don't have a big effect on park lines (though they make a mess of traffic patterns due to the race going all over WDW property.) Anyway, we've gone to WDW in January & February every year for the last few years, and there was multiple discounts available each time. It is very slow for Disney...I'm sure they'll have discounts available. Probably your choice of room discount or some version of free dining.
