It's definitely not Disneyland...but it's ok for Calgary. I get that weather in Calgary would make it difficult to operate an amusement park.
There's really only 2 major rides in this park (river log &!roller coaster). Naturally everyone heads straight to these rides making the lineups very long.
The indoor restaurant is too small and get's overcrowded during lunch time.
Overall it's a decent little park, but after 4-5 hours you'll have seen and done everything the park has. Our family enjoyed it, but there's really rush to go back. The park includes an RV park right next door, I don't know why anyone would go to this park multiple times over a few days.
