Just got back from France Thursday. When you go to Versailles, you can rent golf carts. It’s a must and I highly recommend it.
The Seine Dinner Cruise was wonderful, so I highly recommend that. We ended up skipping the Louvre and went to D’Orsay instead. Louvre another time.
Taxis are hard to get in Paris and the traffic is horrible. We took the metro most of the time. Thankfully our friends had already done it and knew how it worked. It’s doable once you learn it, but they even got mixed up a few times.
It seemed we rushed around a lot to see things on just 4.5 days. When I go back, I’m giving more time to just wandering and sitting at cafes. Visit the Marais district, it’s very nice. I’ll stay there again whenever I go.
