Parc Olympique is exactly the type of attraction you do to say you've done it...but isn't entirely memorable. The view from the top of the Tower is pretty amazing--you can see the entire city from all sides. However, there's not much else to do. Frankly, it was also a little confusing once we got off the Metro. While we were there during the off-season (April), there aren't any signs or indications of what all of the buildings are until you walk in. We bought the combined ticket which granted us access to the Tower and the planetarium. I wouldn't recommend spending the money for this; just do the Tower. All in all, it was kind of upsetting to see how not much is left of the area and to see the aftermath of the Olympics leaving town.
