Don't take a car to Paris, you won't use it. by tmikeyt
Absoultely the Eiffel Tower. There could be no one favorite thing about Paris, it's a wonderful place. Create your own memories. I rented a car at the airport, and promptly drove to the city, where I immediately parked it in a garage until I was ready to leave for Dijon. I didn't use the car a single time. It won't take long for you to figure out the Metro and normally you come out right where you wanted to be. And hey, you are instantly mingling with the locals.
And should you speak little French as did myself, just learn the very basics. Yes, No and Thank you. I used them all quite frequently. It sure doesn't hurt to add 'Can you tell me where is----------?'Hmm, my fondest memory. I can't think of one in particular. Waking up to hotel breakfast of the best coffee and pastries you can imagine, or seeing the Eiffel Tower, sitting at cafes people watching, walking along the streets and along the Seine.
