We are 11 people traveling from Aéroport Charles de Gaulle 2 TGV to La Croix de Berny station, and from there taking the TVM bus for a couple of stops (zone 3).

Does anyone know if:

a) we can buy 1 ticket of 10 t+ & 1 t+ ticket for the TVM bus trip, that means, if we can 10 of us use the 10 t+ ticket at the same time?

b) Can we buy the bus tickets in the same Ile-de-France ticket machine at Charles de Gaulle 2 TGV station?

Thank you in advance,

R. Avila, Spain.
