Planning on just stopping by for about five hours.
We have eurostar tickets between London & Brussels, then Thalys tickets to Paris later the same evening.
Am I correct in thinking we can show the eurostar ticket for the short journey between Midi and Central? And is that all we do, is show the ticket to the official on the train?
And what about the return journey? Can we show the Thalys ticket, or do we just have to buy a one way ticket back to Central station?
On a side note - haven't been to Brussels in eight years - are there still lots of chocolate shops around Grand Place :)
