I am attempting to book one way train passage for May from Avignon to Paris where I'll spend a few days.
When I plug in my destination simply as Paris, TGV asks me to be more specific;
Gare de Lyon (75), Gare de Lyon A or B or Gare de Lyon RER (75).
I am a bit stymied.
Is there that much of a difference between these four choices?
From Gare de Lyon, I will take the Metro or RER to Charles de Gaulle-Etoile.
I will be carrying luggage.
Any info will be helpful.
