I need some options for the best company to use for a private group tour of the Louvre in June 2019.
Well, there is Family Twist. It will set you back 34000€ but then again, you'll be doing it up big time a la the Carters (Jay-Z and Beyonce). https://www.cnn.com/travel/article/private-tour-louvre-paris/index.html If you want a semi-private tour meaning a tour while the museum is open, take a look at the small group offered by City Wonders https://citywonders.com/paris-tours/louvre-tour-with-mona-lisa for about 70€ per person.
JHK did you use this company, city wonders, with a satisfied outcome?
I have not used them. Last fall, very close friends stayed in my place. They used tours for most places. They used Paris City Vision for most tours but City Wonders for the Louvre tour and one other and they really like both tour companies.
Thank you, JHK, this is very helpful!
We did a wonderful tour with Paris Muse. Extremely knowledgeable guide, very efficient but thorough in that massive place.
