@christineH, I just rented a car for July from Hertz via AutoEurope last week, pick up in Florence, drop in Orvieto. So it looks like they are still partnering with Hertz.
@FL doc, we dropped our car in La Spezia before spending a few days in CT. Note: the train station is about a six-minute cab ride from the hertz office. I would definitely take the train to Venice.
Re: AutoEurope, I’ve found their prices competitive, often better than the major car rental companies. I would be reluctant to go through kayak or Expedia in case there was an issue. AE is well known for their service. For example, we needed to add a day to our rental in Italy. I made a call to their toll-free number, a real person answered in two rings, the rental was extended at the original day rate I was quoted, I received immediate email confirmation with revised paperwork…all in less than five minutes. I can’t imagine trying to navigate that at a local office or especially via Expedia.
Rental rates are outrageous for this summer…3X what we paid a few years ago…and rising everyday. I would book asap.
