I see a lot of people torn between the Holiday home (because of its code and design of the place) and the hospital (because Rudy fell down) for the dark world of chapter 6, even suggesting that maybe it's both in the same chapter. But honestly? Knowing Carol, I feel like she would just demand the hospital staff to move their work and Rudy over to their home. (It might even be how we get to see more of their bedroom) Thus, we can have both the Holiday Ice Palace and Rudy revived via darkness.
I actually think we have evidence that Rudy is home.
When Noelle picks up the phone the first time, she says:
But think about what this means.
Surely, if Carol opened with "Come to the hospital, right now", Noelle's reaction wouldn't be "What? No, no, I can't right now...", surely Noelle is smart enough to realize that if she's being called to the Hospital, that Something Big is Happening.
I think this has to suggest that Rudy was taken home for hospice care. Maybe the hospital staff are working from there now, but, more likely, his condition is critical enough that there's nothing else that can be done.
The JP version of the "Fell down at the festival" line uses the same sort of phrasing as the Alarm Clock dialog does for Rudy having "fell down", which would support the idea that he has Fallen Down in a monster biology sense.
And, well...
Even in UNDERTALE, with actual magic and science working in tandem, a Fallen Down monster is effectively already dead. So, it makes sense to transfer him home. There is nothing more that can be done for him.
The Holiday Manor Dark World is Real. Just as I foresaw...
