Our group consists of 20 students, aged 15-17, accompanied by 2 of their professors. We are coming to Paris on 22-25/4/2020. Can there be a more economical overall price for us if we all book our Navigo weekly passes online as early as the last week of January? We would be grateful if your company afforded us the lower cost, as in this way we will be able to spend our limited budget on more of the fascinating sights of the city!
There are no group Navigo Pass discounts, but there are discounts for tickets available for school groups.
Here's the instructions/information on school group discount tickets for Paris Metro/RER trains.
