I got myself a Starling Card (I'm a big Halifax clarity fan) and it's brill for me - I transfer £s from my UK bank account online on my phone (to Starling Card) sitting on the hotel balcony, go directly to Calis/Fethiye ATM and take it out in lira in resort - no interest, great exchange rate, all done and dusted in no time.
Still use the Halifax Card, mainly for purchases/restaurants, but for cash you can't beat the convenience of Starling. And you get interest on any money sitting in the account.
