I went to the park last Wednesday as a part of a family vacation, I wasn't expecting much (after reading some reviews I was almost scared to go), but the park wasn't as bad as I feared.
Goliath is one hell of a ride. Just as good as Behemoth despite being 50 feet shorter. The turnaround had some nice lateral forces, and the last couple hills were pretty good too. The airtime was great. A solid 9 to 9.5 out of 10 for me.
Vampire was pretty good as well, it was my first Batman clone, but I had an general idea of what to expect. It was a pretty good ride, the first three inversions were great. The mist at the end also felt pretty good. It was pretty intense, but I don't have many B&M Inverts to compare it to.
Monster was something I wasn't expecting much out of. For the most part I was right, but there was one drop that had amazing airtime on it, right before the helix, on the right side of the track (not sure if the left side has it as well). I was not expecting it at all, but it was the one bright spot on the ride. As for the rest, eh. It wasn't painful for me, but it was uneventful. Fun, but not thrilling. 7/10.
Boomerang was my third boomerang clone, and it was a bit better than the rest of them, but still, it was just a boomerang. Not too painful surprisingly. 6/10.
Cobra was the most painful ride of the day. I think it has a decent layout, but there was quite a bit of head banging. Not to mention the whole ride feels isolated from the rest of the park, the queue line feels like its in an abandoned parking lot. 5/10, and that's being generous.
The SLC and the Vekoma (either Vekoma or Arrow) Corkscrew was down for the day. I saw some trains running on the corkscrew, with some people in the line, but apparently it was closed. I didn't bother with Dragon or the Wild Mouse, both had long lines, and I didn't the rides warranted spending 45 minutes waiting for.
I didn't get a flash pass, but I think I would have managed to get on all the closed coaster in one day without one, given the lines. Goliath, Vampire and one side of Monstre were running two trains, all the bigger rides were running one. The longest I waited for was 45 minutes on Vampire, but they added the second train when I was halfway through the line.
The one thing that this park has going for it is it's amazing setting. The observation tower was down, but from Goliath and Monstre you could see Montreal very well and the old bridges as well. I saw a couple big boats go across the St. Lawerence, you're literally right on the water. The island located does make it a pain to get into though, (coupled with horrendous road construction), but it certainly is unique.
Ride operations were bad as expected. The ride ops seemed to lack any enthusiasm for their job, and many rides were understaffed. The boomerang had 1 person running it at one point. It left a bit of a bad taste in my mouth at first, but you get used to it. The only 'nice' employee we met was the guy selling Beavertails (which are delicous BTW). I noticed a lot more arrogant teenagers here than in Canada's Wonderland, but not much line jumping (maybe 3 times in the whole day) or other rule breaking that I feared, but be warned.
Overall, the park exceeded my expectations. If you're expecting a French Canada's Wonderland, you'll be disappointed, but La Ronde does have a decent coaster and flat ride selection given the space restrictions, but if the operations got stepped up a notch then the park would be much better.
Hope you enjoyed reading my first trip report
