I am considering Le Louvre shore excursion while docked in Paris, but at $289/each, I'm wondering if it is wiser to book this direct? We have 2 days in Paris at the beginning of the trip, and will be walking distance to Eifel Tower. So I assume a quick cab to the museum. Does anyone have any suggestions if it is pretty easy to visit on my own, and save some of this trip fee? Thank you!
