One of my favorite travel experts out there is Joe Brancatelli . Last week he did a piece for Portfolio.com on rental cars, and how to get the best deal. Even though I've travelled a ton, somehow I'm always confused at the rental car counter--I get insurance amnesia--am I supposed to get it? Which one am I supposed to not take? Well, this piece not only answers that and breaks down many other mysteries, but also shares some booking sites that can apparently save you tons of money. Check it out!
