I've stayed in many hotels where security required you to show a keycard, either to enter the property grounds or at the entrance to the main hotel building. Sometimes just flash the key, other times with a full check of cars, bags, etc. for explosives/weapons. Sometimes basic hotel security guards; other times you can tell it's more sophisticated security professionals.

I've stayed in Vegas hotels that checked keycards near the elevators. That's probably the closest analogy to this. Not necessarily a terrorism threat or protection for a VIP, but just deterring loads of drunks from getting to the floors.

I've stayed in lots of hotels that required you to use a keycard inside the elevator. This by itself doesn't prevent guests from bringing people into the hotel, but it's a modest deterrent against random people being in the halls.

I've stayed in tons of hotels that had many different reasons for security, and none needed to treat me like a boozed up college student to accomplish their goals.

That would be a huge upgrade to the Courtyard brand, regardless of whether or not a new hotel is built.
