Hello! What is the best way to get to Beauvais Airport at night? We have an early flight and would like to enjoy Paris as long as we could, so we'd like to leave to the airport as late as possible.
There are extremely early shuttle buses to Beauvais from Porte Maillot Metro/RER station (i.e. 03:00) so perhaps that would work for you. (There are no better options for public transport to Beauvais from Paris unfortunately.)
