Expensive
Having had the pleasure of flying with HH a few years ago, he made it clear in the flight deck on the way back from one of his European journeys that Dubai will make its money from the expacts currently accomoddated there and the ones to join.
So its no surprise to me that all these matters are being discussed now. It's like a trap that has just closed up. For those with families it si not about the sticker price anymore, but rather more about the convenience of having to move again, finding schools etc....
And ...... its not going to get cheaper!!!
