The instructors have to be able to spot you in case you do something dumb that might cause you an injury. It's not as dangerous as skydiving, but you can hurt yourself.
Levitationarium is an old design. SkyVenture is more modern and should have much smoother airflow. Check out http://www.bodyflight.net/ for details of wind tunnels around the world. There are quite a number of SkyVenture locations, as well as several other independent wind tunnels designs out there.
