Bruxelles, oui ou non?

For reasons known only to myself (I'm baffled), for my holidays next week I've decided to fly into Nice and then travel back via Marseille, Paris and Brussels. I fly in on Tuesday 28th, will stay in Nice for a few days, move on to Marseille on the 31st, stay a few more days and then from there take a train down to Paris, where - after a three hour break - it's off to Brussels, arriving in the early evening. I'm travelling first class, so it should be fairly comfortable.

From there I have two options. Go straight on to Amsterdam, which is another three hour trip, or stay over in Brussels, and the next day go photo hunting and have lunch at Scheltema before catching the train back home.

... can't seem to make up my mind.
