Compare DCA's introduction to DHS'.
DHS: You are the passengers on a most uncommon elevator about to ascend into your very own episode of The Twilight Zone.
DCA: You are the passengers on a most uncommon elevator about to take the strangest journey of your lives. Your destination? Unknown. But this much is clear: a reservation has been made in your name for an extended stay.
Then the imagery we see in the ride.
DHS: The window at the end of the hallway transforms into black and white window from the 5th Season Intro. The doors close silently, we slowly rise up.
DCA: The Elevator at the end of the hall opens to reveal the 5 ghosts. They drop. The elevator drops. Then we drop.
In the Fifth Dimension Room we are surrounded by imagery from the show. E=MC2, the giant fake eye, the floating window, etc. No such depictions in DCA's.
At the bottom of the drop tower.
DHS: Treated to a silent clip of elements of the TV show being pulled into a vortex.
DCA: Pushed back into reality.
The original version is more closely tied to the source material and tells us openly we are in a TV show. The DCA version removes almost all of the TV show references and focuses on the ghost story aspect. I personally prefer the ghost story as it seems less cheesy to me.
