I will be travelling solo to Belgium in September. I'll essentially have one week: 6 nights in Ghent, 1 night at the Brussels airport. The current plan is to spend a couple days exploring Ghent itself, do day trips to Bruges, Antwerp, and Lille (with a quick stop to see the Kortrijk Begijnhof on the way), then see Leuven on the way to the Brussels airport hotel on my last day. Of course, that may end up being plenty already. However, on paper at least, that leaves me with another day to play with.
So my question: would I be crazy to skip Brussels? I'm usually a city guy. I enjoy cities with nice architecture and museums/churches and good restaurants. I know such a question is highly subjective, but I've heard very divisive things on Brussels. I was thinking of visiting Mechelen instead. Or perhaps, going to Brussels, briefly seeing the area around La Grand Place, and then moving onto Mechelen for the afternoon.
Again, I know it's highly subjective but I'd love to hear your thoughts on this.
