For people planning to attend the symposium, please check here, and see whether it might be less expensive to fly and rent a car than to drive.

The rates are good for the conference dates, but not for Sunday, so it would also involve staying until Monday, which you might have planned to do anyway. Or you could spend Sunday night in Albuquerque.
