it's worth Paris Museum Pass?

That depends to a considerable degree on how many of the sights covered by the pass you expect to visit. The PMP is considered a good value, as such passes go, but I've learned that I move through museums much more slowly than average, so passes do not usually pay off for me. The more time you want to spend soaking up the Parisian atmosphere, the less time you'll be spending inside museums and other attractions.

There are some non-quantifiable benefits to having the pass:

• It may put you in a faster-moving security line at a few sights (Musee d'Orsay being often mentioned).
• It allows you just to pop into a place you're not sure about, since your entry fee is already covered.

Have you put together a list of what you might like to do in Paris, even tentatively?

How many full days will you be in the city?

It depends on what you want to see! Take a look at the places the pass covers and see how many of them you plan on visiting anyway.

For most sites, even if you don't buy the Paris Museum Pass, you can go to the museum's website and buy a ticket online that will allow you to skip the line. So if for example you only want to go to the Musée d'Orsay, you wouldn't need the pass -- but to avoid standing in the loooooong security line, you could purchase your ticket online in advance (plus a small handling fee, well worth it for your time in my opinion).

But look at the sites listed as members of the Museum Pass and see if you plan to go to enough of them to make it worthwhile for YOU.

I think it has good value , I've used it a few times and always come out ahead .

I like revisiting big museums so not doing a death slog of hours through one to justify the ticket price .
I like visiting some museums I might ordinarily have passed on .
I like using the clean feee bathrooms in museums .

As Pat said, I think a big advantage is that it allows you to make multiple visits to the huge museums like the Louvre and Orsay without feeling that you have to see as much as possible on one visit.

My personal feeling is that the two-day pass often isn't worth it, but the four and six-day ones very much are.

Also check the website and look at the full list of places covered, as it also includes a number of chateaux within day-trip distance from Paris that are well outside the city, like Chantilly, Fontainebleau, and Ramboillet.

We used the two day pass on our last trip to Paris and it was worthwhile since we packed in quite a lot in just 2 days use. We've also purchased the 4 day pass a couple of times. Definitely worth it if you plan on visiting museums & other sites. As others have said, check their website to see which places you plan to go & do the math to see if it makes sense for you. (It likely will.)

I really appreciate your input. I have another question.

There is any benefit purchase the pass online or is the same as purchase in the central Paris Tourist Office?

I'll really appreciate your thoughts.

I have no personal experience, but I have read on this forum that there's an extra charge for shipping if you buy the pass online. There doesn't seem to be any reason to do that. You can buy the pass at a tourist office (if you happen to walk past one at the airport or elsewhere), at a FNAC location, or at one of the participating but not-busy museums.

It looks as if you've already made your decision, but I thought I'd add that, despite all the times I've visited Paris (some of which, admittedly, have been for business), I have never purchased a museum pass. I've never even looked into it because I don't find the cost of museum entrance to be a major determinant for my decision-making. I'm not wealthy by any means, but the cost I find upon entering museums is not exorbitant. Others may feel differently.

No need to purchase online. We purchased ours at one of the small museums we were visiting.

I mostly come down on the same side of the issue as Bob, but that's because my list of activities is not as overwhelmingly focused on the sites covered by most city passes as is (apparently) the case with other tourists. Also, when I go to a museum, I usually spend more than twice as much time there as other folks. Obviously, that makes me a poor candidate for most passes.

However, I've occasionally bought a sightseeing pass in a small city (Orvieto and Padua come to mind) that gave me plenty of time to see as many of the covered sights as I wanted to see without having to skip other things I wanted to do. Those can save money. I absolutely adored the 6- or 7-site bracelet sold in Toledo. You can use it as long as the bracelet stays on your wrist (I kept it there for two days.) They were all small sights, but very nice, and most came with a short bilingual tour. But most tourists (alas) blitz in and out of Toledo on day-trips, so the bracelet wouldn't be a smart purchase for them unless they for some reason planned to skip the major sights that aren't covered.

An additional point: Folks over 60/62/65 (it varies) should be aware that they'll normally pay full price for the pass, whereas individual sights sometimes offer discounts to "pensioners". They can be quite small, and they're sometimes limited to EU citizens, but occasionally they sharply reduce the entry fee. There are also sometimes good deals for students and/or youths. Those discounts make a pass (which is probably marginal at best) much less likely to save money,

Also: I don't think I've ever seen a post from a traveler who said he got to see more things than he expected. Quite the reverse: We commonly end up missing some of the places we planned to visit. So I think the odds are against making a big-city museum pass pay off. But I'm sure some people manage it. And there are the non-quantifiable benefits, like free toilets.

We stayed in Paris for 5 nights last Spring and thought the pass was definitely worth it. We were able to see more attractions we never would have if we didn't have one. Came out ahead money wise. We bought it at CDG airport at a desk near the arrivals.

Do you plan to visit Versailles ? By itself this takes up a chunk of the museum pass cost.

But also a major part of the validity period of the pass.

Another yes vote for the museum pass. At some of the locations, entrance is expedited with pass. I also like the fact that you don't feel you need to stay a certain length of time in a museum/attraction to "get your money's worth." There's the mindset of, "Well, I can come back later." Or, having limited time left in a day, you could enter one of the locations just to see if you'd like to return.
On our last visit to Paris, we bought our passes at a tourist kiosk outside of Notre Dame. The pass is not activated until your first entrance/visit.
And as another has posted, it's totally worth it if planning a trip to Versailles, Louvre, or climbing Notre Dame tower,...and the added bonus of free toilettes!

If you use it well, it's a great value. Using it well means perusing the sights that are free or reduced with the card and creating a sight-seeing plan that takes full advantage of those. I normally plan two major sights in a day. At that rate, the card is about a break even proposition. If you add smaller sights that may take only 30 minutes to visit, the card more than pays for itself.

Some considerations; don't have a valid card on a day when all the museums are free. That would be a complete waste. Plan sights that aren't covered by the card on the days you are touring without an active card.

It really starts with deciding what you are interested in seeing. Once you decide on the sights, you can compare their individual cost to the cost with the card.
