We will be in Amsterdam for 3 days and have read about the advantages of the Holland Pass. This pass is not mentioned in the 2013 edition of Rick Steves' Amsterdam book. Is there any info you can offer on this pass? It seems to be more flexible and cheaper than the I Amsterdam pass.

The last time we were in Amsterdam we didn't use the "I Amsterdam Pass" or any other pass and found that we still were able to save money overall. We saw quite a bit and walked practically everywhere in lieu of taking the bus. It was good getting out and walking. We took the boat through the canals and it was not expensive at all. You can check at the desk at your local hotels and get discount passes to museums and other interesting sites in Amsterdam.
