Making a reservation for the D'Orsay was easy and transparent, and the e-reservation came through immediately. Thus I was able to print it before I left home.
However, the Louvre e-reservation took about 24 hours to be delivered, which meant that I was already in Paris by that point and unable to print it out. I had my iPad, so I could show the reservation on the screen, but for someone without a smart device it may have been a problem.
Moreover, it wasn't clear why the reservation was initially flagged as "in preparation" - only when I had the small print elsewhere in the Louvre booking pages did I discover that e-tickets can take up to 48 hours to be processed and delivered. It would be helpful to make this more transparent, I think.
On the whole, the site is very convenient and useful, and I would recommend it. I shall certainly use it again - but 48 hours before I leave home!
