We bought our 2-day museum passes thru RailEurope (at the same time as our France rail passes). They've arrived, but the instructions aren't clear about whether the pass must be used on 2 consecutive days, or on any 2 days within a period of time. Anyone know? Thank you.
Two consecutive days. For the latest details on what the pass covers, various hours, and what may be closed, check the pass's official website at http://www.parismuseumpass.com/en/home.php
