I know this might sound like I'm over-itinerizing but I am visiting Paris from 5 May to 7 May with one experienced but elderly traveler (my grandmother, 84) and her cousin, 69, who is visiting Europe for her first time. We'll only have two nights in Paris so I want to maximize their time and the "wow" factor without exhausting them so I'm trying to really trying to plan the arrival day to make the most sense. We'll be coming from Germany on a 3 hour TGV train arriving at 14:26, staying at the Hotel Darcet at the edge of Montmarte. We're arriving late enough that I don't think attempting a big museum makes too much sense (maybe I'm wrong? They want to do the Louvre and Orsay, although I might try to talk them out of the latter in favor of the Orangerie, as they're not really "museum people" and I feel like two massive museums might not make much sense on such a short trip.)
My goal for this is to get them to the Eiffel Tower around 20:00 or a little earlier, so we can marvel at the base and take pictures while there's still daylight, and hang around until the first sparkly show after dark viewed from Trocadero.
Assuming we're ready to leave our hotel by 15:30-16:00, that gives us a nice time window. We'll need to get dinner during this time but they're not gourmands and a nice dinner is lost on Grandma in particular. A crepe might do, or a sandwich, although someplace to sit would be nice, too.
I'm torn on these options:
-Exploring Montmarte and Sacre Coeur right away in the afternoon sun before taking public transit directly to the Eiffel tower. Possibly visiting the Musee de la Vie Romantique
-Heading straight to the Arc de Trioumpe, then walking or public transiting down Kleber to Trocadero
-Heading to Clemenceau then walking/public transiting up the Champs Elysee then down Kleber to Trocadero
-Do you have a better idea route to hit some highlights and best use our time without wearing the ladies out too much?
Again, the goal is to see some pretty stuff, eat something tasty (but not necessarily a proper restaurant) and arrive at the Eiffel Tower no later than 20:00.
Thoughts?
