Thanks all... this has been v.helpful - and interesting to read the debate!...

I think i'll bring some jumpers etc ... and see what happens - although on the debate - often it's the type of cold that makes it cold - my friend from Alberta, Canada - used to ridiculous tempretures was soooo cold when she was in UK because the humidity was different! ... So perhaps that's why?

Anyhoo - i'll think about getting a vehicle too!

Thanks for the tips folks, and welcoming me to Qatar - only 6 weeks to go!
