I have a (pay at location) reservation with pickup from SAN and return to LAX. Duration is 21 days and I’m a President’s Circle member.

I know now that my plans might change midway through the rental, meaning that I’d want to return a little earlier (say, three days) and to a different SoCal location. I will definitely NOT know prior to the start of the rental.

Obviously, I’d need to contact Hertz if this happens; but does anyone know if this is possible and how Hertz reprices the contract?
