I will arrive Paris on Sat.18 May in the next week and stay for 5 days until Wed. 22 May.
Can i buy weekly Navigo pass before on Sat. 18 May and use it later on Mon.20 May?
If I visit Foutainbeau and Verseille Palaces on Sun. 19 & Mon.20 May , which kind of ticket should I buy if i can't use Navigo Pass on these days?
Thank you so much for your kind support.
