We were in Paris for 5 days and purchased the PP. You do get into many museums, but moving to the front of the line did not happen. We waited for at least an hour to get into the Louvre, expecting that we should have been in a line for PP holders was not the case. We also found that we really didn't need to ride the Metro much as we were within walking distance to most things and only used it a few times. The boat ride was nice, but I think we probably overpaid for the PP for what we ended up actually doing. Probably a good deal for some but not for most.
