From my experience, I can tell you that they are not kidding, nothing will be running. There might be some patchy service here and there but don’t count on it. Also, at least on the 25th, everything will be shut. All stores, off licenses, everything. It’s really the most depressing time to be traveling. I’ve got a bit of PTSD from being locked out of my room wearing nothing but a t shirt and underwear on Christmas Day, approaching strangers trying to borrow money for a pay phone. Your post was a trigger!
Can you borrow a car from a neighbor and make sure you are on the insurance? If you asked me, I would do it for a friend. How about zip car? You could join for a month. Beware, the mileage can be pricey.
