Amsterdam
They just reopened the Rijksmuseum after a multi-year renovation. I was there is 1985 and it was great. Just like the Van Gogh museum-a good choice

Take a tour of the Heineken Brewery
Go listen to great music at the Melkweg, a fantastic place with large amounts of pot and hash shared

Brussels
INCREDIBLE chocolate just like their great beers. Go to a fancy chocolate shop and drink some specialized beers you can not get here like some Trappist or Abbey, Duvel-which I really like, or any of the Belgium only breweries.
You may want to steal a few of the beautiful stemware you get with your beers-I took so many steins and mugs when I left Europe in 1985
Shopping in the Grand Palace is pretty cool as well.
have fun it's a great place.
