Special Car Rental Rates If You Stay True To The Same Company from Island to Island?

The title says it all: Do any companies offer special car rental rates for Hawaiian Cruisers if the cruiser stays with the same company from island to island? Just curious. I guess I could call each company and ask, but perhaps someone knows right off hand if there is one.

I've never heard of any special rates for that reason, but if you are a 'preferred' member of any of the car rental agencies, you may get a special rate that way. We always book through Costco - just booked intermediate cars that way with Avis for $45 on Kauai and $55 in Hilo (one day rentals - much cheaper than tours!). Because of the 'preferred' status, you also usually get your car faster as there are separate check-in lines.

We have rented on multiple islands (on a single trip)in Hawaii through Hertz. Never seen any sign of a discount.
