Here's a question for the OP: If "open should mean open", does that work on the other side too? Should "closed mean closed"?
Example ... MK "closes" at 7pm. But Main Street shops are open well past that time. People in line at 7pm can ride a ride, even though the park (and ride) are officially "closed". People are allowed to slowly wander out, take photos in an empty park, etc.
So ... if "open should mean open" and everything at MK is open whenever the park is (EMH or not), then it stands to reason that "closed should mean closed" and when the posted closing time comes, everything in the park closes. If you're ON the ride, you get to ride. If you're in line? Sorry, we're closed. If you're in a shop buying something, please finish your transaction. For everyone else who is still looking and shopping, I'm sorry ... you'll need to leave, as we're closed. Want to stop for a photo or two in front of the castle? I'm sorry ... all of the castle lighting has been turned off, as we are closed.
Thoughts?
