This looks like a fantastic holiday. I've visited most of these places over the course of the past five years during the course of independent cycling trips with a couple of friends and each year there have been some memorable places and experiences. The painted monasteries are breathtaking, though not for the faint hearted as probably every way of being burnt burnt to death is depicted as well as beheadings. The cities of Brasov, Sibiu and Sighisoara are so beautiful and relatively unspoilt. Make sure you get to rural Romania without delay before modernisation and and compliance with European Union regulations destroys their way of life.
