I haven't really had any problems here with smoke smell in rooms in years. Suites used to be smoking, but that was a long time ago. I'm more annoyed by the high humidity in the rooms (get the windows unlocked, see upthread). In any case this is nothing like say GH Macau, where you're pretty much guaranteed fresh smoke coming in from neighboring rooms and hallways.
Breakfast at the lounge is top notch here. I prefer it to most restaurant breakfasts. The standard is lounge breakfasts for Globs, but I have a friend who's a regular and can eat in the restaurant. He took me a couple times, and I didn't find it preferable to the lounge.
