Try Tunisia. It's a little bit different and you get to see Camels!! The quieter parts of Greece are really good too, that way the louder ones in the group who fancy going clubbing for one or two nights can get a cab into town. How about Lyndos on Rhodes? Faliraki is miles and miles and miles away so it is quiet there, the beach is beautiful and there are still bars and stuff. Or maybe Kos. If you stay in Kefalos it is really good for the tan! It is a windy island so it is cool even when it is hot and again, a cab ride will take you to Kos Town at night just to see the harbour and the clubs and late night bars.
I haven't got a clue where the black sea coast is so I've probably made a right t!t of myself now ain't I?!!
