nothing as long as it is in the designated area like your husband is doing...my question was when it is done in public spaces which is what our family saw. Sounds like your husband is respectful of others...no issue here
I saw no one doing it in public spaces, and even if they were, isolated incidents are no different than people sneaking smokes (for example, I caught people sneaking real cigs all over the parks).
This is one issue where Universal has handled it much better than Disney has.
I suppose they forget that the reason why Disneyland originally had trash cans every 30 feet was because, if provided a receptacle within use, people were less likely to litter...
The same goes for smoking. If offered areas, they are more likely to use them. If not, they are more likely to sneak.
I've smoked on all my trips (though I have done the vape and gum thing as well)...and I find a lot of it rather silly.
At resorts, it should be banned around the food courts, main walkways and the pools, for obvious reasons.
At the parks, some more care should be placed on where to put them. For a variety of reasons...part of which is that not the rest of the world has the massive self-rightous "anti-smoking" mantra as the US does.
Smoking stinks, it's dirty (and this is coming from a smoker). Vaping is not. That said, it isn't worth the drama it creates. I've had people walk by me in smoking areas make snide comments about how "it's a children's park", etc...
Well, tell that to Walt.
And, don't give me this "we know more now than we did then" or "it was a different time"...
It isn't. Smoking is a popular thing for people to pick on, and the virulent nature of some (not all) non-smoker's objections is beyond irritating.
All that said, if Disney made their parks 100% non-smoking, I'd obey it (bet people cheat left and right, but I wouldn't). As it stands, vaping is to be relegated to smoking areas, and I think that's ok...but it's really not fair. I've seen people smoke joints in the parks (yeah, weed)...it's not my job to police them, nor is it my role to be overly self-important and complain about it.
