The car was in fine condition. No complaints there. Routes car rental doesn't have a clearly marked desk at the airport. Instead, I had to call a number and they directed me to talk to the folks at the desk of OK Mobility. They had no idea about this rental. I had them call the Routes number again to talk to the fellow there. He said the magic words to them, and they figured it out and I got my car. But this would have been a disaster if I hadn't just gotten my Croatian SIM card just then. Additionally, they did a hard upsell to get me to buy their full protection plan. Not sure that was worth it exactly, but a couple hundred euros later and at least the pick-up process was over and we had our car.
