Looks like a very nice venue, but it is too small. Currently, the Orleans Arena has the capacity for 9,000 people or so, and last year, they had close to 7,000 people in the audience for the Mr. Olympia finals. Las Vegas has been an incredible successful city to host the Mr. Olympia, because of the capacity of a myriad of hotels, the convention center, and of course, a large enough arena. Besides, you can make a vacation of it, seeing lots of things in the city too.
