Mallorca- resorts like Shagaluf put off many people, but there are absolutely incredible parts of this island in ther mountains, and also the area around port adndratz. evrybody should go to mallorca. It's got a great climate, fantastic food, is geared for tourism without being tacky (if you avoid the nasty resorts) and it's cheap and easy to get to. Same with Ibiza (if you avoid the touristy towns).
Cyprus- ayia napa and limassol are fucking shiteholes, but go to the north of the island and it is AMAZING.
Turkey- dalaman an dthe like aren't very nice but Istanbul is brilliant and there are really pretty little seaside ports like Kas which are worth exploring.
i have loads more but I am bored now so over to you.
