Well, Palazzo's casino and some other public spaces are open.
We got back from Las Vegas on Saturday - I was really hoping to see the insides myself. So much of the exterior needs work but I guess they were just determined to start the cash meter.
Update: Thanks to Mark for sharing some exclusive photos with us. You can see them here: http://www.ratevegas.com/photo/gallery/palazzo
Updated Again: I just booked two nights over the opening weekend so we'll be reporting on the full Palazzo experience.
