My daughters, ages 6 and 4, want to ride this ride. I've shown them the videos on youtube, and tried to explain that it goes a bit fast and could be a little scary. They really want to ride this ride when we go at the end of Feb. Thoughts? They both meet height requirements, I just don't want to be "that dad" who took his kids on a ride like that, only to end up having them crying and screaming. I've never ridden it. Is it bad? Looks pretty tame for a coaster.
