I just spent a total of 10 days in three different non-smoking hotel rooms and vaped in all of them. It didn't occur to me that it might set off a smoke alarm, since smoking cigarettes in the past never did. I did use my low-vapor m401s most of the time, just in case my non-vaping roommate might be bothered, although she swore she couldn't smell anything.
I also vaped in the rental car with the windows up, and very stealthily on the plane, in my seat. On the plane I used a mini with a barely damp cart. That satisfied my puffing habit and gave me a little flavor but produced so little vapor it could hardly be called vaping. Really I was just sucking on a metal tube, I guess, like a baby with a pacifier. (It was a nine-hour flight, otherwise I wouldn't have done even that.)
