Often I will see something to the effect of "This property is 100% smoke free" to me that means no smoking anywhere whether it's on a balcony, by the front door or even by the dumpster. Othertimes I'll see "This hotel is 100% smoke free." Now, I'm all for semantics but I really believe the hotels mean the same exact thing in each of those statements.
Other times (and I think Disney may actually have been one of these) I've seem "Smoking allowed in designated places only".
