Both of us have valid eurail ticket wondering what kind of ticket best for my plan :

Arrival gare du Lyon travel to auber

Next morning from Auber visit Versailles. After that visit Champs Élysées then back to Auber.

Next morning from Auber to gare montparnasse to catch train to Rennes for mr.st.Michel and come back to Auber again

Next morning from Auber to gare du nord station to catch my booked train
