You should not take I-80 in January. The weather could be very bad. Besides I-80 goes to San Franciso not L.A. It s way too far north.Take I-70 to I-44 to I-40 to I-15 to I-10
Motels do take debit cards (if you have a pin)Also, I-80 is a piece of pie in the warm months, you never know when you re going up, or down!I would honestly head south though to avoid the winter, cause the snow will suck.Drive during the day for easy viewing of the road, or drive at night if you just want to drive with the truckers.Also, a good tip is to either get a hotel coupon book right before you re going to stay, and apply for a hotel credit card to save even more. Go to findairlinecards and check out their hotel section for cards that save.
