Actually I think the whole thing has been sort of blown out of proportion. I know it was a real issue for 10 days or so after the last storm, but Currently the only people I have seen getting stuck without cars are people that walk up to a rental counter without a reservation...it has driven up the cost of rental cars on short notice, but all companies are honoring lower rates booked in advance.... as long as you have a reservation I think you should be fine....and by January there should be no problem at all.
