Lovely city, Copenhagen - lived there for thirteen years, but DON'T visit for 'just a weekend'. Unless things have changed a lot, there is a tendency for everything to close at 12:00 Saturday and not re-open until Monday morning.
Tourist centres in the summer are allowed longer opening hours, but a wet and cold Sunday in the capital can be a dismal experience.
And don't forget that the Danes eat VERY early in the evening, you will find it hard to find a restaurant where the kitchen is open after 22:00 - be prepared to eat dinner no later than 20:00, if you want to eat at all (however, drinking goes on until dawn, if you know the all night bars and that is your thing).
