I was in Florida and flew back Christmas Eve. If I hadn’t had a reservation for a rental car, I would have been hosed. Southwest seemed to not have any cancellations where I was flying to and from.
Ubers/Lyfts are cheaper for a very large % of travelers flying into a city and usually only marginally higher if higher. I *usually* skip car rentals at this point, even before car rental prices went nuts, although I did get one for bourbon country tour earlier this year.
