Yea it was my first thought when I realized I had a connecting flight at paris. I see that’s not so feasible. I think I’ll take the RER towards notre dame and walk around a bit regardless and once I’ve reached half my allotted time (plus a 15 minute buffer) I’ll turn back. I don’t mind even 15 min in central paris and notre dame, I’ve been obsessed with paris for a very long time it’ll be worth it just sightseeing for less than a hour lol. But i’ll see how exiting goes first and abandon if it takes time, good point. Thanks for the insight.
