For those who have traveled to Paris recently, I'm wondering if anyone has used the PMP to visit the Arc de Triomphe? I am reading that you can only visit with a reserved time slot. However the online ticketing site states: "The Paris Museum Pass can be presented directly to the monument, no reservation on the internet." There doesn't seem to be an option to reserve a time slot without paying. If using the PMP are you able to ascend the monument without a reserved time slot?
Conversely I was able to book time slots for Sainte Chappelle and the Louvre (both require timed entry) with the PMP so no extra $ online. Sainte Chappelle uses the same ticketing engine as the Arc de Triomphe so it's very odd that you can't book a time with the PMP for that.
Any tips from recent visitors are much appreciated! We will be in Paris 9/30 - 10/4, so will be there for the wrap of the Arc.
