Quick question on Paris Museum Pass

YES! That's one of the great things about it. We went to the Louvre 3 times on our 6-day pass; twice during the day and once at night. See the note about unlimited visits on this page of the website:

Hands down, this was the best pass we've ever purchased besides the now-sadly-limited Friends of the Uffizi card.

Ah yes. We were lucky to have the friends of the Uffizi card when you could walk into any museum ahead of the line including the Academia without reservations. It is now nearly useless unless you are there for a long time. Agreed -- 3 short visits to the Louvre beats one very long visit. Note that if you do just get a single ticket for the Louvre you can go in the morning, take a break mid day and then return in the evening on the same ticket.

Janet and Kathy,

Can I safely assume, we have to go through security each time we enter each museum?

Yes, it's fab. Go to the Louvre both Wednesday and Friday evenings when it's less crowded.

Yes, security check every time you enter a museum.

That was SUCH a great card, Jane! We'd fully intended to make good use of one again for an even longer stay in Florence in the future so I'm depressed that they eliminated so much from it. We almost never buy passes as they're often poor values but that one and the Paris Museum Pass were great buys for our particular interests/time frames.

What is the easiest way to purchase the pass? At the first museum we visit or in advance?

When you have the museum pass you often use a different security line; at the Orsay you use a different door and much of the year you just walk in with no line; the worst line I have been in with tickets ahead at the Orsay was about 15 minutes. The main line can take 2 hours. At the Louvre there is a bypass lane at the Pyramid and at the Carrousel for pass holders; there is a separate security line at the Orangerie and Pompidou. So the pass helps avoid long lines many places. Everyone is in the same security line at Versailles, usually but not always at Ste. Chapelle and you can never skip ahead at the Notre Dame Tower which only takes 20 people at a time.

Yes, you purchase the pass at the first museum you go to, so it's usually best to buy at a smaller museum where the ticket lines are shorter.

Alternatively, you can buy Paris Museum Passes at branches of FNAC, a books/music/IT store chain with many branches in Paris. There's no extra fee and the queues are usually very short.

I'll just throw my two cents in and say I preferred buying the pass ahead of time and having it shipped to me. That way if the Louvre or the D'Orsay happens to be your first visit - you get to skip that long ticket buying line.

I agree with Dave from Phoenix. Buying ahead of time and having it shipped lets you hit the ground running at whichever museum you want when you arrive in Paris.

You can also buy the passes at the airport when you arrive. We bought our 6 day passes when we arrived and "activated" them on first use.
They are a great deal.

We bought ours on day of arrival at one of the lesser-visited attractions it covered. We were out for a walkabout and just stopped in and bought it when we went by; no waiting in line. One caution? You have to fill them out with name and date of intended first use, and you need to use European dating order (day/month/year) instead of how we commonly do it in the U.S. (month/day/year). It's a little thing but one that's easy to forget about if it isn't top of mind.

No, the bigger attractions with long ticket queues - the D'Orsay, Louvre, etc - are not good places to purchase them.

If you're arriving by plane, you can also buy the Museum Pass at the airport.
Others have said it, but I'll repeat: I think it's best to buy ahead of time (not at the first attraction you want to visit) and it's truly unlimited. Use it as many times as you want within the period you've paid for (2, 4, or 6 days). The days have to be continuous once you activate it - you can't "save" a day for later use - but you can re-visit the same place or different places as many times as you want.
