So my wife and I are going to be taking a trip up to Vermont from NYC. We want to rent a car to try and stop her friend who we are visiting from having to drive us around. Anyway, I've never driven the kind of distance in one go that we'll be doing, so what kind of car should I rent for the week? We don't really want to be held to the schedule of others either, so that's why we'll be driving. Thanks!
