We had a few hours one day to fill, so we jumped on the train to Prater. We only rode two rides, the famous Ferris Wheel and Hotel Psycho, but really enjoyed both of the rides as well as just walking around checking out the park. I enjoyed this park because there is no admission, you pay per ride, which I imagine would get costly very quickly with a large family or with kids. With two adults, it was the perfect place to spend a few hours.
