I would not purchase the Brussels card in future. The information desk in the City Hall Square is hard to find, and the staff who exchanged my voucher were grudging at best. I had purchased the Brussels card online before reading the fine print. My visit was from Sunday noon until Tuesday noon. I did not know all the museums were closed Mondays, so I got to see exactly one, for which the Brussels card was useful. That was it. I tried to purchase a discounted Metro pass but that involved various code numbers that a tourist does not necessarily carry around. The Brussels card cost 30 euros and it saved me possibly 5 euros. A big disappointment. The coupons in the booklet might be helpful to some but not to me.
