I also love Holland See my must see places http://www.elitepro-travel.com/2008/10/windmills-souveniers.html
We did Bike and Boat trips in Holland in 2005 and 2010. That is the way to really see, smell, and hear the country. We rode during the day while the boat traveled through the waterways to our next overnight stop. Breakfast and dinner is served on the boat and you make your lunch at breakfast to take with you on the bike. The terrain is mainly flat so the riding is easy; however, the wind could be a problem. We want to plan a trip in March/April when the tulips are blooming. In 2010, we also rode for a week on our own and returned to some of our favorite places that were not on the bike and boat. We rented bikes rather than traveling with them. A GPS was programmed with our route and we also had a map as a back up.
I wrote a long post about the self-guided tour in 2010. This is the link for that post:

If you ever end up in the Hague (a nice town, fascinating history, wonderful Escher museum, and don't miss the Peace Palace), and you're looking to rent a bike, try these folks - they're very nice - I've used them a couple of times:
Because it's so flat, I rented one of their single-speed Cinelli's (something I wouldn't ride at home - it's too hilly). There are innumerable bicycle trails and lanes, bikes are everywhere, and it's particularly fun to ride down by the beach or out over and through the dunes. One day, I rode from the Hague to Haarlem, enjoyed a wonderful lunch at a cafe, and rode back. It ate up most of the day, but it was a wonderful experience!
