Hi Jo,
I am also moving to Dubai together with my wife at the end of February.
I have been there a few times, and have lived and worked in various places around the world.
I am British, and I have found that once you get to know a different place you will find that you have far fewer worries than you first imagine. I currently live in Manila with my Filipina wife, and I would sooner my wife gave birth in a private hospital in Manila. a third world country! than the NHS in Britain.

My new work mates, whom I have met and talking with, all assured me that they have very good health care and education in Dubai, and I have no reason not to believe them.

Hope you enjoy your life there in Dubai, I fully intend to.
