I spent 2 nts in Brasov and 1 in Sighisoara,if I was in a hurry I would have caught an earlier train to Brasov spent the night and seen Sighisoara the following day returning to BUH the same day,but I did enjoy my overnight at the hostel (pvt room about $20 US)in Sighisoara,I found a good beer joint and did not see another tourist.I was there in Jan so the days were short.I caught a good tour of the Castles in the Brasov area from the hostel there (the driver supplied transportation but little narrative but opened up a bit when I spoke with him)the entrance fee's are not included.I would not recommend 4 nts in BUH,get out and see the countryside it's beautiful
