ParisPass

Martha, Like any pass, you will need to do the number crunching to see if it works out in your benefit. if i remember correctly, it doesnt cover any transportation. When i was there, i did buy the pass, but after doing the number crunching. what i liked was being able to bypass most of the ticket lines. Happy trails.

In short, no. You can buy a Museum Pass to cover all the museums and skip the lines. If you buy a separate Paris Visite transport card, the combination of the 2 is less than the Paris Pass. Most people on this forum will recommend you buy a "carnet" which is a book of 10 bus or subway tickets for 13 euro vs 17 euro if you buy them individually. There is also a 7 day pass, but it always starts Monday morning, so if you were there say, Thursday to Wednesday it would not pay as you would have to buy 2. As a family, you can buy a couple of carnets and use them as you need to get on the Metro. Buy another if you run out.
There is never really a non-peak time in Paris.

First, there is a Paris Pass, a Paris Visite Pass, and a Paris Museum Pass. They are three different things, and yes, it is confusing. "I've read that the ParisPass is a great & affordable way to do all the sightseeing you want." I'm not sure where you read that, except maybe from Paris Pass itself. It's very expensive, and there are only 24 hours in a day. So, while they dangle the 60 or 70 "covered attractions," how many can you actually see during the validity period of the pass? I certainly can't see €55 of sights per day (the price of a 2 day pass). The 4 day and 6 day passes are slightly better deals, at €40 and €32.50 per day, respectively; if you are really busy for all those days, it might pay. The Paris Visite pass is also not a good deal for most itineraries. You'll do better with a carnet of tickets (10 tickets, shareable, bought at one time, for a substantial discount over individual tickets). As said above, the Paris Museum Pass can be a good deal. In November, you don't need it so much to skip lines, but it's a good deal if you're seeing enough covered attractions (particularly if you're going to any of them more than once). Here's their official site: http://en.parismuseumpass.com/rub-museums-monuments-by-name-5.htm. However, if you're not going to enough of the covered attractions during its period of validity to make it worthwhile, don't be afraid not to get it (Rick says smart visitors always get it, but I don't agree).
