Does anyone know if the TGV from Barcelona to Marseilles is usually sold out and do prices increase significantly within days-several weeks before departure? I've read Rick's advice on booking train tickets online ahead of time versus at the station and have explored the RailEurope site; unfortunately the site proved very clumsy to use and had much higher prices when I actually got the process to work than were shown on the basic itinerary. So, how 'safe' is it to bypass RailEurope and get my tickets at the station several days in advance?
Thanks!
