WDW February 2017

I am planning on a trip to WDW the first week in February 2017. It has been about 4 or 5 years since I last went at this time and the crowd levels were low. Looking at the crowd calendar for this week I see lots of 7s, 8s, and 9s, which surprises me. Is there something in particular going on during this week that I should be aware of?

Thanks for your help!

Also interested in early February 17, I was kinda hoping to book a 3day weekend near my birthday and crowd calendars looked so high! I miss freelancing, where I could travel mid week.
