Top 10: Brussels, Bruges, Antwerp, & Ghent by Anthony Mason (2014) in anticipation of a trip to Belgium (specifically Ghent) later this fall.
I've looked at DK travel guides before, and this one follows the same pattern (which is what one wants a travel series to do): surfacey, but relatively broad, small nuggets of information, lots of pictures. The size of this guide could make it a nice travel companion and it includes several types of maps, including a laminated pull-out map of the centers of all four cities that can be removed from the book.
I'm hoping to see a bunch of Belgium, but since our trip will be focused on Ghent, I was hoping for more detail on that city, which, perhaps because of its size or academic nature, is the least covered of the four. Still, this gave me a good overview of what is out there in lovely Belgium along with a portable size that will come in handy later!
