Hello Rick Steve's Travel Forum,
I wanted to share a learning experience from the travel school of hard knocks! My family and I had a wonderful week-long vacation to Paris back in November of 2023. However... in order for us to squeeze in a day trip to Normandy and Mont St. Michel, I booked a same day rental at SIXT Champs-Elysees. The total at booking was €318.26 which for a group of 5 seemed like a steal. But when we got back from the trip I had a bill of over €1,600 with over €1,000 in "excess mileage" with added tax. After reviewing the initial booking, I had looked over a small detail that noted "250km of included mileage".
Included mileage is not something that's typically in American car rentals as far as I know so I wanted to share what I've learned. It was an unforgettable day trip for us and well worth splitting the huge bill between the 5 of us. But if you're looking for a convenient way to day trip from Paris, consider the included mileage for car rentals and/or look for alternative modes of transportation.
Best wishes to you all and happy travels!
