Amsterdam is one of our favorite family vacations. Within hours of landing in Amsterdam, we rent Mac Bikes: one with a kids seat and the other a Bakfeitz (wooden box attached to the bike). We pop the kids in their seats and ride around the city for the entire duration of our visit. The best thing about it is that our kids never get bored or whine about walking too much. We make frequent stops to get ice cream, a park visit or restaurant so it's fun for everyone.
