Car Rental

From a travel-savvy Sangha member:
If you're planning to rent a car, which isn't necessary unless you're going to be traveling before or after Festival, and trains and buses won't work for you (and in Europe, of course, public transportation tends to be very good, unless you're going to more remote places), book it with American Express card if you have one because it offers lots of advantages, particularly on insurance.

I've also read on the Internet that a lot of travelers say not to rent from Hertz abroad.
