Did you ever consider to take a city walk with a (former) homeless person as your guide?
Maybe you should, that is if you want to experience more than just the tourist side of Amsterdam. Of course a tour by a homeless person is not all fun and Disney-like entertainment, but it sure is interesting and revealing. And the guides are known to add a good dose of humour as well.
