I traveled to Italy last summer with my family. We found a hotel in downtown Florence that proudly advertised that they had valet parking for only 20-some Euros per day, but they conveniently forgot to mention that if you bring your car to the hotel to get it valet parked, you'll get a fine... It's really a shame that I have to find out about this ZTL nonsense by searching the internet AFTER I receive a large fine in the mail several months after returning home from a trip to Italy... I've traveled and driven in MANY countries around the world, and have never come across anything similar to this. This really smells of a scam of the Italian authorities perpetrated on tourists. Seriously, do they WANT everyone to hate them? I personally am NEVER coming back to Italy again after this experience, and my impressions of Italy and Italians are EXTREMELY negative, in large part thanks to this horrible experience. The car rental company (Maggiore) also omitted this small detail. Not only is there a 100+ Euro fine to pay for this ZTL nonsense, the car rental company also charged my credit card (without asking or explaining) an extra ~40 Euros for "conveying my information to the Police". What a load of crock. Italy -- you've lost my tourist dollars and my respect forever (and from the looks of it from similar experiences I've found online, not only mine). I hope it's worth the ~150 Euros.
