I have been looking at my Paris museum pass from 2009. Am I right in that not all museums on the pass are free thr first Sunday of the month? My booklet shows a red circle if it is free and many do that have that. If so, I will have to plan Sunday's activities around the smaller museums that aren't free that day.
Yes, many museums free on first sunday of month , avoid the Louvre and Orsays, they are so crowded you will want to commit hari kari,, instead use it as a day to see for free some of the museums you weren't sure about visiting, you know that way you aren't wasting money or a day on your pass on them( remember pass is consecutive days, so free day in middle is useless)time pass use before or after .
