Hertz - Question for fellow PC members about combining certs.

I would like to rent a car for eight days next month. Can I combine (2) Free Weekend Rental Certs and (4) Earned Free Rental Day certs to cover this entire rental?

Has anyone combined this many before? I thought I had read on this forum that you can.

There is of course no way to enter this when making a reservation and I have a feeling that if I called the res line and asked they would say no.

For the free weekend you have to bring the car back to the same place you rented from. They can't be combined.

The earned free rental day certs can be combined. I always just enter the PC code into the online reservation and hand over the multiple certs upon return.
