My 2 cents as posted elsewhere:
They are trying to depict luxury in Star Wars, something you NEVER see in the OT, and only quickly glimpse in the other films. The HEROES of Star Wars are never seeking luxury. You don't want to be one of the rich villains, do you? They need to wear-and-tear the whole ship down. Grunge it up.
Or have the place be fancy, but treat guests like they're 3rd class passengers on the Titanic. You can see a poster for the nightclub, but you can't go to it because you're too poor! (ie. You don't have to be subjected to it any longer than you would in one of the SW movies.)
But darn it, that won't work, because you can only afford this experience if you are wealthy. I guess that makes you a Star Wars villain, then. Enjoy your twi'lek entertainment.
This is like setting out to build an Indiana Jones Resort, and having it all look like ritzy Club Obi Wan from Temple of Doom. I mean, yeah, it's canon, but I was expecting a lot more caves, jeeps and skeletons, and less art deco & dancing girls.
