You might want to book now if you are planning Jan. 16th. That is the Sunday in the middle of MLK weekend. I've found that this weekend is generally higher in price for the resorts because of the holiday and sometimes is harder to get a discount at. While the other days should be OK, Sunday and Monday might cause you some problems. I'm a DVC member and I could not get Jan.16th at the resort I wanted and had to go on a separate waitlist for that night. I did get it a month later, but that was in June when I was allowed to book it. Also airfare may be an issue for that weekend too. I've already made all of my ADRs for that timeframe too. While the MLK weekend will be crowded, it should calm down during the week. I find most weekends remain moderately crowded regardless of the time of year now.
