If a new attraction was placed in the station that formerly housed Son of Beast, it wouldn't be a confusing mess. The reason not many know where Flight Deck is is because of the lack of a beacon that draws the crowd that way.
When Son of Beast operated, you would find a train cresting the towering wooden lift hill, with the perilous riders screaming "Hey! A ride's over here! Come over! And you might find a little something next to it!" But now, that area of Action Zone is dead because the GP who only visit the park once a year assume it is just a dead end.
Another thing about that area, it seems like they true to hide flight decks sign. Unless you walk past x-treme sky flyer, you can't even see the sign, let alone the ride itself. They need to make sure the guests know "HEY THERE'S A RIDE OVER HERE!" and one sure fire way to not do that is to tuck the sign of the only ride back there into a little corner. And that sign would have to be one of my favorites in the park:) shame
