If you have ANY scent sensitivity, perfume issues, bronchitis, allergies, asthma etc., do not stay at the Venetian. They openly admit they pump a sort of perfume/air freshener into the casino, hallways etc. They *claim* it's not pumped into rooms, but I'm sorry, you can't isolate smells. It's utterly pervasive. My first room (5th floor) was so bad I thought someone had tried to cover up illicit cigarette smoke (non-smoking room), and asked to change rooms. The second room (25th floor) was only marginally better. There is still a choking, noxious, cloying incense-like smell everywhere.
Thank goodness I am checking out in the morning. My chest hurts and I'm very congested already. I'm not normally that sensitive either, so I can't even imagine how you would deal if you were. Management was completely insensitive to my complaint - basically suggesting they would give me a refund and I could leave (except since my room was pre-paid, no refunds would be allowed). At midnight! One desk person suggested they might be able to give me a room with a sliding glass door to allow for fresh air, but the manager nixed the idea. It was probably some sort of upgrade I assume. Trust me, I could have cared less about an upgraded room - I just wanted to sleep and BREATHE!
Aside from the smell, the hotel is just okay for a Vegas 5*. Big rooms, but the couch is pretty worn and there were garbage bags in the hallway of my first room. In short - it's not aging very gracefully. It's not terrible, but you'll see a few frayed edges to carpets and the occasional chipped tile. I've stayed at Palazzo, Wynn, Bellagio and Trump, and all are significantly better in my opinion (and none stuffed up my nose and chest!). But if it weren't for the smell and , I'd say the Venetian was a step up from your average 4*s but not comparable to the best resorts in town. Location rocks.
