I agree about the Goblet. It's supposed to be an oasis, but it is, without question, the most monochromatic oasis I've ever heard of. My understanding of desert cultures says they like the bright colors as much as possible to break up the color of sand. Unfortunately, all you get in the Goblet is sand coloring and not nearly enough of the oasis/garden theme.
I think if they opened it up so it's actually on top of the mesa like it should be, adjusted some of the views a bit (perhaps by setting it so you don't wind up looking at a boring bit of stairwell on most houses), and gave it more of a real vibrant oasis feel then people would really like it. I know I would.
