I have been traveling in Europe for the last month. It is madness. I'm currently waiting to buy a seat reservation for my eurail pass in Paris Gare du Lyon because Paris Gare du nord could not sell the reservation (it's the same damn company). With the eurail pass, you can get on trains for free, but for some trains you need a reservation, and it is impossible to buy the reservation online or even at kiosks, and there is no way to know which trains require reservations. Additionally, some trains sell reservations but they are not required. And this is nuts: some trains allow you to board even when seats are not available, and you just stand in the hall for the duration of the ride or until a seat frees up. And of course there is no way to know how many free seats are available on the train. Sometimes there may be available seats on trains that require reservations, but the train company only allots so many seats for eurail passholders and you are out of luck. So this is how I am spending my time in Paris.
