I've just returned from a week in Lanzarote, got talking to some of the British staff in the bars, some around my age, asking some questions about the practicalities. Sounds like the money is good, the weather is some of the hottest in the world, plenty of (waiter service) bars and eateries and shops, everyone is dead friendly, no antisocial behaviour, nice rental accomodation and fairly cheap houses if you wanted to buy, regular 4 hour flights to the UK.
Who wouldnt want this over cloud and drizzle, low paid work, queueing at an understaffed bar, fast food culture, unfriendly service (everywhere), antisocial behaviour everywhere, overpriced property.
I have thought about it, and would love to move there, but wouldnt want to be away from family.
