Aside from Brussels, I would like to visit Brugge, Antwerpen, Ghent. How much time do I need for each one? I can skip the art museums because I have limited time, but do want to see the architecture and take the river cruises in Brugge and Ghent to get the feel of the places. Judging by the maps, the historic center in Antwerpen is the smallest of the three, and that of Brugge is the biggest.
I plan to spend one half day in Ghent (about 1:30 to sunset), one full day in Brugge and about four hours in Antwerpen (and two more in Mechelen on my way there). Is this a good plan and enough time for those places, or should I for example spend more time in Antwerpen and less in Ghent?
Thank you in advance to everybody.
