I and my friends visited as a gang on Saturday (May 4, 2013) to this place. We paid $10 per head. Unfortunately, not all tulips were blossomed that weekend. Since we did not go with high expectations, we were not disappointed a lot. It is not a big garden as such, but this is the only tulip garden that we have near wisconsin which suits for a one day trip. The most important thing that I don't like is they do not have proper restrooms. All the restrooms that were available were portable restrooms with no water. Though soap liquid is there, with no water, I don't know what we can do with that.
However, some of the tulips were nice. I have posted some of the photos on my facebook page. Not sure whether every one has access to see, but the link is here https://www.facebook.com/media/set/?set=a.10201145558463347.1073741825.1301261091&type=1
