A lot of the smoke alarms in commercial spaces like hotels are now 2 detectors, the regular ionization and photoelectric. Photoelectric is easy to set off with a vapor cloud. Depending where they mounted it you could set it off with a steam shower if you left the door open. MTL stealth is pretty much the way to go, that or vape in the bathroom and blow the vapor behind the shower curtain. Hypothetically.
I work in a hotel and every fire alarm since I've been there was caused by long showers with the bathroom door open, apart from a couple of nitwits who left the iron on the ironing board. Smoking of either variety doesn't do it. Or vaping as far as I know.
We charge $250 for deodorizing rooms from smoking. But rooms cost more than that. Pissing off a potential paying customer who goes somewhere else next time doesn't make much sense.
In any case we can't do it unless we find actual cigarettes in the room, or butts lying around. The smell isn't enough. Even empty cig packets aren't enough. Normally we just put an ozone machine in the room for a couple of hours. Those things are pretty effective.
If I was vaping in a hotel I would turn the shower on at high temp for a while and get some steam going. And make sure not to leave vaping gear lying around. Seems like a lot of bother though, I just take a walk outside.
