Take A Hike
Save your money. Unless you are visiting with someone in your group with mobility issues, you’ll probably save 50% by walking to the key sights in each area and then taking a group taxi to the next main area. Stop 8&9 are closed and they don’t tell you that in advance. Those 2 stops are the Arc de Triumph and the Eiffel tower. The new temporary stop is a mile from each site. Check their route out before you buy.
