Considering how verboten smoking is elsewhere around the country, you'd think Vegas and Atlantic City would do a little more to help out the non-smokers.
@Miffy I can only assume you are allergic or react negatively to smoke and can understand the trepidation over attending a conference there. It is hard to escape the smoke, but I think there might be one or two hotels on the strip that are smoke free, I'm honestly not sure. Aside from literally running through the lobby/casino to avoid the smoke, I really wouldn't know how to avoid it. The convention centre itself is smoke-free.
