I went with Cyprus Paradise about 6 years ago, and they were good then. The north is beautiful. We stopped at a stall at the side of the road to get fruit one day, and the woman made us have lunch with her - stuffed vine leaves and olives, gorgeous.
It was the best holiday ever.
As someone else said, don't let them stamp your passport. They'll stamp paper if you want them to, they're quite used to it. In the south, it is illegal to go to the north, that's why there is a problem with getting your passport stamped.
