Then we walked to Ibis Hotel nearby Gentily. The bus is very cheap less than 2 euro and bring us from Zone 4 to Zone 1. The next day we bought a Mobilis day ticket to Disneyland.
We avoided the Orly bus as it will me more costly to travel to Gentily. In 2013 a tram line 7 from the airport is open to Villejuif.
Basically from the airport you have the option of taking local bus, Orlyval, Orlybus, shuttle bus to RER C Ponte de Rungis and Tram line 7.
