This is not a true skip the line. You skip the queue to buy the ticket but end up in the queue with everyone else who pre bought tickets line was shorter but only if you go early. The guide does not take you anywhere, just tells you from the office where to go. Annoying to have the audio tour from this company also as you have to return it to them when finished and all people exit the a Louvre at a point further from the tour office than the entry about 10min walk. Easier just to purchase from the Louvre and hand in when exiting. Would be just as easy to buy tickets online and go directly to Louvre and pick up from ticket office.
