Hollywood Studios: Tower of Terror
What if...the Hollywood Tower Hotel was Disney's newest resort? How nuts would that be! Would it have an in-resort drop for guests only?
The lobby would HAVE to be exactly the same as the ride, to keep that vibe, and I would hope that the check-in would have some portion in the boiler room.
If this was ever done, and done right, I don't think I'd ever stay anywhere else. Every trip would be "HTH? Yep."
