I went here early during the week of Tulip Time Festival to avoid any large bus crowds. I was able to take my dog as well. It was a fun little mock Dutch village (I think it would be nice if they put some kind of barrier up to block off views of the highway.)
The grounds were well maintained and all the employees were very friendly. Lots of fun picture opportunities. Watch out for one of the grey geese who likes to chase people around. The shops are full of authentic Dutch products, the wooden shoes and blue & white china. The cafe had some light lunch fares.
I know if my 5 year old niece with me she would have had a great time on the little rides and seeing the few animals also on the property.
