Dubai rocks. My family has lived there for over 20 years on and off. You'll love it. I'd suggest spending a day at Wild Wadi

Good fun.
I'm living in Doha now. The airport is dead easy, everything is in English so you'll be fine transferring. Time difference to Doha is 2 hours, 3 to Dubai and Abu Dhabi. When the clocks change, its 4 hours to Dubai and Abu Dhabi.
Enjoy.
Cheers
