This is one of my favorite flats actually. My easily dizzied aunt says it is her favorite as well. She and I both agree the smoothness, speed, and sensation really combine to make a good, relaxing ride. It fits the theme well too.
It is much longer than two seconds, but not by much. We rode this yesterday and it felt to be the same duration as all the other times I've ridden it. As shown in the video above, it is probably about that long. The longest part of the ride is locking and unlocking the cars. They should have two people doing it like Le catapult.
