We just moved last week. :)
We have shipped (not arrived yet) loads of toys, pictures/paintings and nice things from home. I bought loads of clothes over in the expectation that they would be hard to find in my size (12) but they aren't, and it's very cheap for clothing.
My kids are 1 and 3 so we've just put a deposit down for a gated community. I'm on a teaching salary so can't afford villas etc, but have secured a beautiful, modern house/apartment in an amazing compound (PM me if you need details) for 3000rm. Definitely bargain. Hard.
I won't comment on schools as I am a teacher but if they are all like mine you have nothing to worry about. I'm astounded by how lovely the staff and kids are, and how good the facilities are.
We are hoping to have only the one car, DH is a SAHD and happy to do lots of walking. Haven't really encountered public transport yet. Driving is mental.
We've found the heat very manageable. We spent 2 days in Dubai on the way over and that was so hot that it felt cool when we arrived here! I'd advise against the Dubai route, as the Emirates staff at Dubai airport were horrible and ruined our trip (I feel an angry thread coming on!)
Anyhow, got to get to work now, but feel free to ask more. I've found that everyone is really friendly, and really willing to help you out and show you round. So happy with the people I've met so far. :)
