Thrifty Complaint - Can't Waive "Optional" Insurance in Europe
Don't rent from Thrifty in Europe unless you're ready to pay 15 Euros extra per day for "optional" insurance. Their requirements to waive the insurance are so complex that unless you've done a lot of homework upfront, including getting a Gold or Platinum Mastercard (NOT Visa) you'll have to pay. I had coverage through my American Express Card, my personal auto insurance, a Platinum Visa - all of which were not acceptable. 15 Euros per day for insurance is excessive.
This is way more than enough to cover any potential liability.
