We are going to be in Paris for 4 days/nights. On Day #4, we’ll be on an all-day Fat Tires Bike tour to Giverny. Therefore we got 2-day Paris Museum Passes instead of 4-day. I know that gives us 48 hours of use from the time the pass is activated with our first entry. The third day of our visit is a Friday, and the Louvre is open until 9:45 that evening. I reserved a 5:30 entry. This means we can use our passes for things after 5:30 p.m. on our first day in Paris, all day on our second day, and all day on our 3rd day until they expire after our entry into the Louvre.
The Rodin Museum is open until 6:30, with final entry at 5:45. I couldn't fit the Rodin into my plans for the second or third days of our Paris visit, but thought we might use our passes to go in at final entry on our first day, for a brief 45 minute stroll through the museum.
When we get to the Louvre on Day #3, for our 5:30 reservation, I assume we’ll have to wait in an entry line despite having a reserved entry slot. If it’s after 5:45 by the time we get to the front of that line, will we be denied entry because the pass expired? Or will we be allowed to go in because our reserved entry time was when the pass was still valid and we’ve been in the line? If the former is a risk, how many minutes in advance of our reserved entry time would you suggest we get there?
