I'm surprised you are even asking- O'leary is the DEVIL
Abu Dhabi is a great place, more refined than Dubai, but growing rapidly. Etihad will look after you and your family, and educate your children!
It is VERY hot from about the start of March through to the end of November with and from June is very humid too (but everywhere is well air conditioned).
the UAE are pretty liberal states too- and there is a thriving expat community.
Good luck!
