It is indeed a "big thing" moving your family to Dubai but at least, once there, their days off will all be spent with their family rather than losing half of them commuting home every week. For those pilots I'd suggest there isn't a lot to think about. Ryanair seem determined to carry on driving pilots away with basing policies and, more lately, no chance of any summer leave. For many it may be a case of, "may as well just go and live in the sun".
Good luck to them.
