I’d made a reservation well in advance, but a few hours before I was scheduled to pick up the car, I got a text saying that there weren’t any cars and I could opt into a waiting list or cancel my reservation. I called Hertz to see if they’d switch the reservation to the airport, where there were many cars available. They refused to do so at the price we’d agreed. They wanted to increase the price by 125%. When I asked if there was a supervisor I could speak to, the representative hung up. In the end, I had to buy an Amtrak ticket last minute, at great expense. The lesson from this story: don’t use Hertz, perhaps try to pay in advance, or just stay home.
