Cons: Without consent or notification, my credit card was charged $200 when I picked up the car, then charged the $54 rental when it was returned the next day, along with another $200 charge. I contacted the number on the Budget receipt, who said those charges were "authorizations" and would come off. It's been 6 days, and still no pending transaction reversing the $400 in additional charges. They're also showing up in my credit card detailed billing as "purchase", not "authorization".
Cons: unfortunately I was 20 minutes late for my drop off on a Saturday which most locations close at noon and are closed on sundays.. which is strange seeing how a lot of people rent cars on weekends. So I drove 2 hrs to SAN Francisco to drop it off at the airport and was charged an extra $300. Enjoyed working with Hertz but not happy about that. Also drove to a closer location before going to SAN Francisco but when we got there it was no longer a Hertz.
