The issue with having RAP load from the exit side is that it can often reduce throughput, which I’m sure the park would want to avoid on their “new for 2023” attraction. A throughput reduction resulting from RAP guests being batched in from the opposite side would be particularly problematic with a ride system like Duel’s that relies on quick dispatches.
You also have the issue that walking a wheelchair up that exit likely isn’t very pleasant, and could cause some crowd flow issues.
Yes, the changes made in 2021 were very poorly received on the whole, but at the same time, accessibility and equal provision are very important cornerstones of the modern day theme park, and the original Drawing Room was not equipped to handle disabled access.
Simply bunging disabled guests up the exit arguably provides them with an inferior experience and could be construed as not providing “equal access” to the whole experience of the ride. Therefore, I think the changes needed to happen at some point to allow for that accessibility.
With this in mind, I predict that the room will be turned into something entirely different that both fits the new ride experience and allows disabled guests to access it too. I would not mind betting that the changes in 2021 were made in a slightly slap-dash manner because they knew that the ride was getting a larger refurbishment in 2023. It is worth remembering that that change was forced upon them rather abruptly due to COVID rules preventing them from sending disabled guests up the exit, as well as the ensuing backlash that resulted from Duel not providing disabled access at all in 2020.
Also, this ride will not be the Haunted House or Duel. It will be its own attraction with its own unique qualities. With that in mind, I think it might be nice for that room to be changed to fit the attraction’s new identity.
I do hope they put a staff member on the ramp to merge RAP guests into the queue in an orderly fashion, however…
