SDD was fun and mild. However, I was a bit surprised by the first turn up the hill. Both times I rode I was sitting on the left, and if you look to your left I think it could be a bit much for some people with a fear of heights. I'm scared of heights, but oddly not on rollercoasters so it didn't bother me one bit. But my nephew (11) rode on that side once and said he didn't want to the next time.
