Has anyone booked a private tour of the Louvre after buying a timed ticket? I can’t seem to find info on Louvre website.
All I can find are the group tours to the Louvre. They give you the option of booking just the tour or the tour and admission.

IF you want a private tour I'd consider contacting Paris Walks to see if they can provide you with a private tour based on the time of your already-purchased ticket.
I am not finding an option for private tours provided by the Louvre itself at present.
We had a guide through With Locals. We bought our ticket separately. Emilie was our guide and did a nice job.
