Would appreciate comments about taking barge trips.
Any particular area in the Netherlands? Do you have a length of time in mind? Are you trying to find out what they cost/where they travel/if they are any fun? Do you have your (approximate) dates of travel set? The more specific you can be, the better the responses to your question!
Rick probably considers barge trips to be too slow for him most of the time, but he did seem to enjoy himself on the Burgundy TV show: http://www.ricksteves.com/watch-read-listen/video/tv-show/burgundy-profoundly-french.
