Well, you've got 2 things working against you there.
A.) Many schools haven't started back up from winter break.
B.) That weekend is the WDW Marathon. Many participants and their families will be arriving around that time and its a quite popular place....not to mention the carb + protein loading possibilities.
Check on-line reservations and call them occasionally. If your heart is 100% set on Ohana's then try doing that every couple of days or so. Worse case scenario, you go without an ADR and ask if your party can be accomodated. You might be pleasantly surprised.
The parks will probably not be that busy unless you're talking about Martin Luther King Day weekend, but 'Ohana is an extremely popular restaurant. The marathon doesn't add that much to the park crowds, but it does to the restaurants.
Check online reservations every day or so. I booked the majority of my ADR's by phone about 3 weeks for February 3-11th and asked at that time for Chefs de France and there was no availability. Been checking online a couple of times a week and yesterday I was able to get exactly the day I wanted originally.
