I have to say, from flying across in a research airplane that was not allowed to measure (so no work for the scientific crew = lots of time to move from window to window and observe) - it is a colourful country and very beautiful from above. There is black and white, and red and yellow, and the many patterns in the sand and the mountains are interesting. I didn't know they had (extinct) volcanoes either. If I wasn't a woman I might have even considered going.

It feels like a destination for the hyper-wealthy to Americans because our tourist offerings here are so much better - but not everyone can come here. My best analogy for Dubai is that it's like Vegas without the gambling - and while that may suck for some people, it can definitely be done. Vegas is also done at every price point!
