I am trying to figure out how to purchase train tickets from Schipol to Bruges on the IC trains. Do I book through the Netherlands train site or Belgium’s? Also, I understand that I can travel on any IC train to my destination that day. Does that mean if I purchase an 11:30 ticket I can get on the 10:30 train if I’m early, or only later trains? I am also assuming there is a cost savings if purchasing early? Thanks to any and all who have traveled this route and provide input!
