Planning for Belgium

I was to have been in Tunisia for a meeting this spring but it had to be pushed back to September. In the process of losing the date we lost our venue too, so with the new date comes a trip to Brussels.

Anyone any advice? If Geri joins me at the end of my 3 days of meeting(s)...

We're (OK, OK, I am... ) as usual starting with a more ambitious list of spots we'd like to spend at least a few days in: Brussels, Lille, Bruges, Ghent, Maastricht, Antwerp, Amsterdam. Then if we use Icelandair again, a few days in Reykjavik on the way home.

We'd be training it and as we'll be spending days in each a small hotel or B&B will be a better fit than an apartment.

The best we can recall of Brussels we zipped through it on a train.

So, any suggestions or advice?
