The boat bus
Amsterdam Airport now offers a link-up for flyers on layover to take a floating bus tour of Amsterdam's canals.Now for some fine print: you've got to be on a layover of at least four hours, and prepare to spend some 45 minutes of the 2.5-hour tour out on the water in something that floats but totally looks like it shouldn't. Prices are 39 Euro per adult or 19.50 per child.
