I'm planning a month long European road trip for my wife and I next summer and would like some practical advice concerning car rentals. Seems like there are more Europeans here than the other forums I visit, so I'm asking here. Anyway, I've been googling and getting price quotes from some of the bigger players in the biz. The prices for a car plus insurance seem expensive, but not unaffordable, but then I started reading travel advice sites and saw more than a couple warnings about unexpected rental costs in the form of fees, taxes, etc. I very much prefer no surprises on a trip like this, so any shared experiences would be greatly appreciated. The plan for now is to arrive in London and leave from Rome about 28 days later. From what I've seen, no one will rent a car in England for drop off out of country, so I'm thinking we'll pick up our car in France when we get off the train or ferry. So, the car will be needed for about 25 days and ~2500 miles as we make our way south. Staying in France, Germany, Austria, Switzerland, and Italy and leaving it in Rome at the end. Combination of highways and back roads, not spending a lot of time in major cities. So, what don't I know? I know what the car rental place is quoting me and I have a rough idea what fuel costs will be. I assume there are toll roads but I can't imagine they would add significantly to the overall price of the car. What else is there? Thanks in advance!
