We go to Pennslyvania every year, but never made it to Dutch Wonderland until this year. I thought it was great! My younger daughter and even my older son enjoyed all the rides. I thought it was only for little kids, but they had bumper cars, a couple of small roller coasters, and lots of other rides that he could go on. I loved the Sky Princess roller coaster. We must have gone on that thing 10 times.
The only thing I didn't enjoy was the admission price which I thought was kind of high. For about the same price you can go to Hershey which is much bigger. But if you are in the area and want to take the kids to have fun, this is wonderful.
We went for the free preview the night before a couple of hours before the park closed and we were able to go on a lot of rides in just those few hours. We enjoyed the Frog Diving Show and there were a few other shows for the little ones.
