I'm from Toronto, but I've been there a couple times. It's the only cable park I've ever been to so I can't really say how it compares to other parks. I can tell you that it's definitely a fun time though. I would make a weekend out of it though rather than just a day. There is a water-park right next door, which comes in handy when your body needs a break from wakeboarding. There's other stuff to do there too, like volleyball, kayaking, paddleboating, etc. It's fun to just chill out on the beach, or by the pool with a beer when you just want to relax. Just a heads up though, the beer is expensive, and the food is terrible. I would venture off-site for lunch if I were you. There is a little town called Saint-Eustache about 10 minutes away where there is a motel, and a couple decent places to eat.
If you're ever in the Toronto area, more specifically Peterbourgh, let me know!
