Hi! 

My friend and i just tried to book tickets for our trains back to holland, for one train we could, but for the other one it said that the tickets were unavailable. When i went to the site of the company itself (eurostar) i could still book tickets there, but i couldnt get any interrail discount and they are suuper expensive. Is there any way i can still buy tickets without breaking the bank? 

Thanks in advance.
