We will be in Paris Dec 25 - Jan 1. Our itinerary is below - we are a family of 4, two kids ages 11 and 15. I'm wondering if I should book Orangerie, D'Orsay and Seine cruise tickets now or closer to when we get there (or even once we arrive). Other sights we plan to see are already booked, but I am not clear if for these three pending items they fully book in advance or not. In case our itinerary changes slightly, I thought I might wait - but don't want to risk not visiting these places if I need to lock them in earlier.
For the Vedettes de Paris Seine cruise, can we purchase these on whichever day we go? Or do these cruises book up?
