This is a great deal if you want to see a fair number of museums and places of interest in your stay. 24 of them are free with the card and others are discounted. That's a fee boat trip, free Belfry and Dali Exhibition, free Brewery Tour (de Halve Maan), and so many free museums from the Memling (fantastic medieval hospital to the Groeninge (all flemish art) to the Choco-Story and the Friet(chips) museum. Every major museum is included so you can dip in without taking any risks. There are discounts off cycling, ballooning, buses and much more. It costs €33 for 48 hrs and €39 for 72 hrs.
We just enjoyed ourselves walking the canals, eating and drinking and seeing whatever we fancied - and somehow we saved €30 each on two days of entertainment, without really trying. The Belfy & Dali exhibition are €18 together to start with - so you can see how the savings add up quickly.
You may be given a card if you're in a grand hotel but the rest of us end up buying one - and it's great value!
You get a visitors' guide with it too.
Buy the card at the Concertgbouw Information Centre (on T-Zand) and at the Station Information Office. Details on www.bruggecitycard.be
