You realize how ridiculous that would be, right?
You realize it wouldn't make anyone safer, but would totally destroy the whole point of vacation, right?
You do get how unworkable it would be under any circumstances, right?
You do realize that even if you did that, what would stop someone from attacking an entrance with security and metal detectors?
You do realize that WDW's business is destroyed with one mass casualty attack, even if its in the parking lot of one of DD's hotels, right?
You are never safe. Just a sad fact of life.
