What site do you all go to for Euro car rentals? And how do you handle the insurance part of it? Buy one of the yearly ‘insurance for car hire’ policies?
I start with Kayak since it has almost all sites, and then start drilling down into deals.
But really, there are only 2 online travel companies: 1. Expedia and 2. Priceline. All the online brands roll up under them. It's a duopoly.
However, you should also look at the individual car rental company sites too - and not just rely on the "two" engines. Sometimes you find a deal.
I still have a Corporate Code for Hertz from an old job, so I use that sometimes.
Insurance, I am not the best one to comment. I play a little loose. Generally, I use my credit card + personal auto. This does not work in some countries, so I will purchase additional.
