My sister and I visited Belgium last August. During that time, we were able to travel by train for reduced fares--perhaps even 2 for 1. I don't recall if that was due to our advanced ages or if it was some sort of 'promotion' just for that time.
I believe I first got wind of this 'special' on RSForum, but cannot recall.
We will be back in Belgium for nine days in April....and we were wondering if the reduced fare will be in effect during that time, or if someone could possible suggest where to look for the answer.
