I had an interesting experience with the lap bar. The first time I rode (during the auction rides) I sat in the last car, first middle seat (is that 8-2 or 13-1?). Anyway, the attendant had to physically push down on the lap bar to get it to lock and I was in tight. There was no air on the ride and I was hugely disappointed.
The second time, I sat in the second car, second middle seat (2-3 or 3-2) and there was plenty of space after the bar locked and I got huge air and really loved the ride.
Are there specific seats for larger theighs or perhaps I was just sitting differently the second time?
I wanted to add that both times the safety indicator line (or whatever it's called) was at the same place - just visable.
