This Hertz rental location ( I believe a franchisee) is at least a poorly run operation, and I suspect very likely a shady one. Have rented many times in Ireland with other companies and never had anything occur out of the norm...Not so for this rental....
Part 1: Rented car via Orbitz and took the insurance offered by Orbitz for $77 for the week with no deductible. When I arrived to pick up the car at the Hertz counter the gentleman asked me if I wanted their insurance for $44 a day. I said I already had the insurance, to which he replied...not with us, which was of course true. So, I explained to him that I had purchased it thru Orbitz. He then turned to the "dark side" in tone and demeanor and told me he would put a 5000 Euro hold on my credit card to which I replied...that's fine. And, apparently put off that I hadn't been bothered by the hold, he told me...This is the way it's going to work, you damage the car you will be paying us, and you can chase your money from Orbitz...to which I replied...that's fine.
This was not the warm Irish welcome people expect, and which we received in every B&B, shop and pub throughout the entire week we were away from people at Hertz.
Part 2 (the "shady" part): Returned car with full tank of gas and no damage. But, the receipt I was asked to sign for (and did) had two interesting add-ons which were not in the summary provided by Orbitz...30 Euro for an "administration fee" because I did NOT take their insurance, and 5 Euro for a "credit card fee" which I assume they charge to all but the .005% of people who pay cash for their rental car. The word "thieves" quickly comes to mind, but I am not going to use it here.
I let Orbitz know what they were up to and without my asking they credited back most of what the Hertz team made off with.
Please believe me, I won't be dealing with those Hertz Shannon Airport shysters again. Ugly bookends to another great trip to Ireland.
