OP, I went to Dubai in 2001 and DH and I were actually quite unnerved by how shiny, soulless and empty it was THEN, so God knows what it's like now if you think it's got worse...
I don't like shopping and I don't do spa treatments, we only went there because it was an airmiles freebie. Would never, ever go back. Sure, the restaurants were amazing, but it was too damn hot to step outside the hotel. I spent most of the 4 days we were there lying in the kids pool under the big sail shade there, reading propped up on my elbows, as it was the only way I could be outside and not expire from the heat.
Also I felt deeply, deeply uncomfortable there. There's a real undercurrent there if you're a woman - I hated being on my own there, even if DH popped to the loo when we were in the hotel bar I found myself being 'cruised' by the locals like I was a prostitute (I hasten to add I was very respectably dressed, the aircon indoors was too damn cold to not wear sleeves!).
And to top it all, on the plane home some Saudi couple were sitting in our seats and even though they were in the wrong place WE were made to move (to single seats nowhere near each other) with no explanation other than 'they need them' - they weren't seats near a loo or an exit, or with extra legroom, just 2 together, for 2 fully-functioning adults who were incredibly rude and arrogant but had the attendants dancing over them like they were royalty.
So no, we won't be going back.
