Maybe, but if it also keeps guest safe...
I'd rather go through the minor, and it is minor, inconvenience of going through a metal detector than getting something dropped on my head.
No, what roller coaster do you have to go through a metal detector to ride?...seriously, this makes a terrible impression on first time guests...
I'm not going to go through airport security just to get on a ride...if the ride is experiencing that many people getting hit by objects the ride needs to be shut down and reevaluated
There are tons of coasters with vertical lifts and over crowd moments...this is so 2006 Universal...ridiculous
