I wouldn't bother trying for a mileage run now. The prices are high for last minute runs, especially with the holiday season.
Why not do a mileage run first thing in January? You can easily make a weekend run to either ZRH or NRT with no hotel stay. Leave Friday night or Saturday morning and be back by Sunday night.
If you sign up for the Gold Challenge, a run to ZRH/NRT will easily get you the necessary 5k Q-points.
