My issue is more the lack of clear directions *after* the first scanner. There's a SO in front greeting guests, telling them "strollers over here, keep your backpack on, just walk through, have a nice day!" After you walk through there's nothing.
So you either continue walking into the park and then three SOs walk up to you "Sir, SIR SIR SIR!! You need to go over there for additional scanning. HOW DARE YOU TRY TO SNEAK PAST ME!!"
Next time you enter a park you walk through the scanner and await further instructions only to hear "Sir, SIR SIR SIR!!! keep walking STOP HOLDING UP THE SYSTEM STANDING THERE HOW DARE YOU!!11"
Clear and consistent instructions would avoid that.
