ABRIDGED VERSION don't rent from Hertz if you do not want to pay for your spouse/partner as additional driver, the one star is for Hertz as a corporation not the folks working at the counter, the two I dealt with were nice guys but suggest they work for another car hire company.
UNABRIDGED DIATRIBE..........
I booked cars in both Belfast City Airport and Heathrow and specifically verified before travel that I would not be charged for spouse as additional driver which is a benefit of Hertz Gold and AAA.
Belfast City Airport - After a 10 hour overnight flight from the USA's left coast and a connection via Heathrow, we just wanted to get to the hotel, instead I have to spend 30 minutes telling the Hertz agent, a very helpful personable young guy, that I verified with Hertz before leaving the US that spouse would be free and I am not paying 9 pounds per day more for an additional driver. He figured out how to remove the charge. The car was a Nissan Micra, a tin can of a car, with a big dent in one of the doors but it did not break down so that was a plus. When I return the car, a different Hertz agent, also a friendly sort, assures me that I will have no trouble in England because it is in the "U.K"...HUH? Last time I checked Northern Ireland was in the UK, he says this is Ireland and the rules are different. But despite his sincere assurance that Heathrow would not be a problem, it was, once again 'computer says no' and we go through the same routine all over again..... see my review of Hertz Heathrow for the details.
The poor Hertz employees are the front line, they should not have to enforce ridiculous policies designed to confuse customers (and the employees themselves). I do not fault the employees.
Hertz needs to standardize its policies world wide and eliminate the additional driver fee for spouses/partners. I recently rented from Avis, no charge to add spouses, domestic partners, employers, employees or companion drivers for disabled renters. Good riddance to Hertz, I also cancelled the "FREE" Hertz Gold member that starts to auto bill $60 annually after the first year, canceled the membership (which was not that easy...another 30 minutes of my life wasted) read more
