...but leave the streets and the Tower as they are, after all it's probably the last attraction done with such care and and a broad appeal.
It's an amazing attraction, both outside and in. From World Showcase, it blends seamlessly into the backdrop of the Morocco pavilion. In DHS, it's what draws you down Sunset Blvd and it gets more ominous the closer you get. Once you're in the queue, you feel as if you are really standing outside of an abandoned hotel (my kids even asked me if it was once really a hotel). Upon entering the doors into the lobby, you "feel" the history (as fake as it may be) that led to this hotel's demise. The elevator doors, especially the one with the "Out of Order" sign elevate your anxiety. Even if you've ridden it a thousand times, your heart stops as the thunder cracks and the lights go out in the library. The details and sounds of the boiler room suggest that something unusual is about to happen. And the ride itself is magnificent, from the doors closing, to the hallway, to the 5th dimension, and finally the drop(s).
I've been a passenger aboard that most uncommon elevator many times and it is still as exciting and breathtaking as it was for me the first time I stepped through the doors of that elevator nearly 20 years ago. It hasn't grown stale. On the contrary, it each time I'm there I see new detail and appreciate the ride even more.
I like GotG and I'd hope to see it have representation in DHS (beyond a clip in GMR). Done properly, a GotG re-theme of ToT could be okay--but I can't imagine it being as epic as what has stood in DHS for nearly 20 years. This rumor must not become reality. If it is because of licensing with CBS, then it'd be simpler to remove/replace references to TZ (mostly the Rod Serling narration, and props such as the doll and the reference to Anthony Fremont at the Tip Top Club). Otherwise, leave the creepy hotel struck by lightning story sans TZ references and the ride still works.
Of course, I'm speaking of the DHS ToT. I have similar, but weaker opinions about DCA's ToT. With the exception of the mirror effect, DCA's ToT is inferior to DHS' ToT, both outside and in. I'd hate to see either ToT become a GotG attraction, but I'd be slightly less sad to see it happen in DCA.
