I don't know how much the ticket is now...the goleif.nl site should have the latest price. By train? didn't look into that...i would image you have to do multiple transfers...it would only make sense if you wanted to see all the places along the way...
yah..the price increases very rapidly..the flight I booked for 229 last friday is over 600 now...so...lessons learnt..book quickly coz it rarely drops...
