We went for residency just because we did not have to worry about going over/home every 3 months, I thought it would become a bind. We have not been back to the UK in 1 year, went to Rhodes but that is expensive and nothing to make me want to go there every 3 months. The Mais trip is cheaper but very quick.
I think it possibly depends on whether you plan on regular trips to the UK as well. We do see plenty of people arranging their trips en masse so that can be a help - although I am pleased we do not have to bother. I could add that we do not drink spirits or smoke so that is not of interest either, and friends do get us a few pork chops (and Cadburys chocolate)
if we want them.
You pays yer money ............
P.S if you are not sure why not try the first 6 months or year by doing the trips. It will be Winter when you come so I think your only option in Turkey will be Mais, but I may be wrong.
