If you're planning to buy direct from
DVC, you can ask your salesperson to check availability beforehand. If it means making a sale, you never know what sort of magic they might be able to work.

You probably won't have your choice of resorts on such short notice--Saratoga Springs is the most likely to be available. With regard to February, the week after President's Day is likely to be the toughest to book now. Other than that, the rest of the month tends to be fairly slow.
Good luck.
