There are lots who have registered in Cyprus with BC in the past, very few active members now - click on Books and Memers tab at the top, do a search for members in Cyprus and order it by number of books registered. Having said that, you may rekindle some interest there or even have your books caught by another holiday-maker. My best catches are usually in touristy areas. Have a great holiday.
Oooh if only there'd been bookcrossing when I was living in Cyprus!! I'd suggest touristy areas too - Troodos and Omodos, Aphrodites beach in good weather....themed releases in some of the historic open ruin areas would be awesome. Can you tell I miss island life? :)
