Trust me: visits to HW that are "not the best" are the exception, not the norm. You'll have a great time. And Voyage is running much, much better this year. Don't miss it. For airtime, I recommend the very back seat (yes, I just recommended a wheel seat; that's how much smoother it is).
When I rode it two years ago I just couldn't ride it too much because it was very rough. I've seen some reviews of it with the re-tracking of the turnaround area and apparently it is very good!
