Just a bit of caution. We rented a car from Autoeurope in September, 2013 in Venice in order to visit Croatia. Picked up near train station, dropped off at the Venice airport. Had an uneventful trip, came back, dropped car off and went on our way. We returned our car within the time limits agreed upon and didn't think about it after that. Luckily, I checked my credit card bill a few weeks ago and noticed an additional charge since we had prepaid for the rental. I called the company and was told that we turned in the car late(3:30) and were charged an extra day. We did not return late, but needed to prove the time we did return. Unfortunately, my husband had already shredded the receipt. Much to our good fortune, I was able to contact our hotel outside of Venice and they sent proof that we had checked in at 1:03. That did the trick and we received credit.
Anyway, please be on the lookout for any additional charges that pop up. Also, DON'T shred anything for at least two months. Hopefully, my husband will listen to me next time as I warned him not to throw anything out for a month!!
