While not at all answering your question, i believe personally that it is a bit selfish to CTB in a hotel and have a hotel employee walk in on it. The scene of your overdose/hanging/self inflicted gun shot wound would cause them a tremendous amount of nonrecoverable trauma.
I always read this point of view on almost every threat involving hotels. And this isn't anything personal against you, I'm sorry if I sound like I'm trying to be mean to you, I'm not, I love ya;)
I just want to say, yes, the hotel employee will have to walk in on your dead body in a suicide scene, in some cases gruesome ones looking. And yes, it's sad, and it can leave the person shaken. But can we stop saying stuff like "it's selfish" and so on? It's death. It's never easy, suicide or not finding a dead body is still a hard experience, though admittedly suicide is harder to witness. But it's alright. Death and even suicide are natural. Dead human bodies are natural. Someone is gonna have to see your dead body one way or another anyway, through suicide or if you die a normal death someone is gonna find your body at some point in time, tomorrow, 10 years from today or 50. Will it be the police officer, a hotel worker, a morgue worker, or just a passer by because one suddenly dropped dead on the street, it's gonna be someone and they gonna have to deal with it. It's really not that big of a deal. Suicide and death are reality, trying to avoid it and pretend it's not something that happens is not gonna solve anything, it's not gonna make it go away, and it's not gonna solve the reasons for why people kill themselves. If one finds a body after suicide you just have accept that this is reality, it has always been this way, just because you personally haven't come across it, doesn't mean it never happens. At the same time, it doesn't have to influence you more than just knowing the fact that suicide is real influences you, a suicide of a stranger has no personal connection to you, it doesn't have to leave you traumatized unless you let it.
My point is, their is enough shame and blaming and self hatred going around in suicidal people's heads as it is, there's no need to be creating more. This isn't right or just to say that it's selfish because a hotel worker will find your body, in this way we can find a reason to shame ourselves for everything for literally breathing and existing(ex. because our life is too hard and pain filled for somebody normal or happy to witness and it can leave them shaken and even traumatized). We all share this world. We all have the right to be in it and be as "problematic" as however "problematic" we are. We share this world, there's no avoiding leaving somebody else shaken or traumatized even for witnessing whatever point in our personal lives they found "disturbing". We can't be responsible for other people's well being in regard of witnessing everything this world has in it, the ugly and the pretty. Besides it depends on the person, even if I wasn't suicidal and found a body after suicide I would feel shaken up but I would move on, while someone else might have a harder time moving on. It's not our responsibility, we can't put a blame for literally everything that our life experience does to others on ourselves, we can't control it, therefore it's silly to blame yourself for it. We have a right to suffer and we have a right to express our pain and we have a right to do things the pain makes us do. And if it's hard to witness for somebody else-that's not our fault. It's just us the way it is. The answer here is not to try to hide our pain and every expression or sign of it from the world because it's disturbing to them, the answer here is that we have to accept that it is the way it is, it's not our fault, and we share this world, each of us has the right to be as messy as however messy we are. Life isn't always pretty.
And as to whether the "do not disturb" sign will still work the same in these times, I'm not sure but maybe try asking the hotel if they are obligated to ignore it right now or will you be able to get some peaceful sleep time, tell them you are really tired and prefer to rest I disturbed? I'm not sure if this won't sound too suspicious but perhaps I'm overthinking this and it will sound normal. I feel like it might be normal.
Love,
