Gutted that I am on holiday for the Bruges fixture. Went to Bruges and Brussels for a few days last year.
Flights to Brussels are fairly cheap. Hotels in Brussels and Bruges are also fairly reasonably priced. Bruges is about 1 hour on the train from Brussels. Good (and extremely strong) beer is plentiful anywhere in Belgium. Bruges is very picturesque and well worth a look around but you will struggle to find too many bars open for long after the game.
For those who like a post match night out check out when the last train to Brussels is. Decent nightlife and cheaper hotels than most European capitals. Beware 10% beer is the norm and makes for an almighty hangover.
In Bruges is compulsory viewing beforehand.
