I don't know what it is about Amsterdam, but people seem more laid back, at ease and just so damn happy - in a rather understated way. I guess it must be a lifestyle. This may have been just me but it also seem very family oriented in all that they do. From seeing little family units biking around the city for leisure or on their way to work or school drop to family walks, family gatherings in cafes and for the sake of enjoying each others company. As vital as visiting the canals or the many museums in the city, a stop to Vondel Park is another must. We couldn't help but stroll through Vondel Park.
Note that you can also rent bikes from within the park. The rentals are close to the entrances.
