I'm of the I love Dubai brigade.
It's architecture and ventures like the snow dome (an indoor ski complex!) are points of interest for our students. When I'm super duper rich inshallah I'm going to stay at the Burj al Arab because that is also an architectural anomaly half submerged in the sea (is it still, ex brother in law said it wasn't after the Tsunami?).
Go as a tourist it's a mix of the new with all the good and the bad that goes with westernisation and the old and traditional.
The mosques are beautiful (but I find those gorgeous anywhere in the world), and waking to the sound of the adhan resonating outside makes ones heart ache.
A bit of advice, if you go to Dubai go during the winter months July till August is too humid to stand. If you wait till January they have the shopping festival which is fun.
But other than that it's worth seeing.
