Tried it. Left for EK in 2003, returned to UK 2006. I was hardly ever at home. EK works you to an early grave, after 6 months of sun wife was bored to tears. As for schooling, our daughter was in a good school ( J.E.S.S.) thought she was doing well as she was in the top end of her class, now back in the UK she is playing catch up.
All in all we are all glad to be back in the UK. EK was the worst move we ever made.
