Do NOT rent a car from Thrify at the Frankfurt Airport. They send you a company called Terstappen, which will triple your rates. They will not accept VISA or Mastercard for CDW. They charge your credit card 600 Euros for a 'damage waiver' and do not refund it. We were quoted less than $200 on the Thrifty website for a two-week van rental. Total credit card charges came to over $1700. I am not kidding. We are fighting it, but every time we get the charges removed by Visa, Terstappen charges them all over again. Do not, do not, do not use Thrifty or Terstappen at the Frankfurt Airport.
