Crystal maiden , it ' s like in men in black when you look around at all the scary dangerous aliens . The one who looks the sweetest is generally the most dangerous . <| sep |> You ' re going to want to be on the LyonBarcelonaMadrid TGVAVE line then . It ' s clearly the best way to train from France into Spain dear lord the old Talgo train was slow . That basically means Perpignan , Nardonne , Beziers , or Montpelier . I would also stick to the advice that it ' s going to be far better and more economical to just pick a place and fly from Prague and then fly to wherever you are going in Spain . It ' s a six and a half hour train ride on the high speed from Montpelier to Madrid , for example . Maybe if you ' re going to Barcelona , but even then , Vueling is pretty cheap .
