This ride is very very smooth, probably the smoothest in the park, especially next to Gwazi lol. As the PP mentioned, it is not as intense of a roller coaster and I find it more "family friendly" but none-the-less, the ride is great! Wait times, I went opening day, when I got off, it had a posted time of 180 minutes, granted once we entered the queue after 4 hours of waiting, we had about a 20 minute wait.
Last week when I went, in the morning it had a 90 minute wait, a little later it was down to 45 minutes, and around 5 it dropped to 25 minutes which in reality was only 10 minutes.
