This article on the future development of MGM's Cotai project is a great view into what's wrong with a lot of modern casino design. Grant Bowie runs the operations for the company there:
We are searching globally for what are the world's best practices and, more importantly, what are the world's biggest consumer trends in global tourism and leisure destinations.
... we don't want to make the decision of what it is going to look like yet, and specifically how we interact with the consumer, because in the 18 to 24 months that it takes us to get to that point in the design cycle, in high likelihood trends may have already changed.
Sure sounds like this will be a place built by focus groups.
Needless to say, I prefer the 'auteur-in-chief' approach that Wynn Design & Development uses for their projects. They may not always suit everyone's taste but at least they express someone's vision, not some conglomeration of 'trends in global tourism and leisure destinations'.
