I've seen a couple great recent reviews on her, and didn't see much of concern. I agree, early reviews concerned me.
I'm sailing Oct 4, and the only thing that I'm still concerned about is the casino smoke. I've always had an issue with that on all ships I've been on. It seems like you have to walk thru casino to get places, and smoke hits me like a wall. My concern with the Venezia reviews is that smoke apparently invades other areas of the ship.
I'll reserve judgement and hope it's not bad.
