One week travel between Bucharest and Brasov / Romania

Hi people,

I have planned a one week trip to Romania, from Firday to Friday, and after some thinking, I've decided to stick between two "bases": Bucharest and Brasov. Not to keen on spending alot of time travelling during the trip itself, which is why I left some places out.

I have pretty much planned something like: land and spend a few days in Bucharest, -> visit Sinaia on the way to Brasov via train, -> continue to Brasov via train same day -> spend time in Brasov -> then either return for one last night in Bucharest or travel same day as flight.

Initally I have planned Fri-Sun in Bucharest, having Sunday as the travel day, then spend Mon-Thur in Brasov, then travel back to Bucharest on Thursday.

What do you think, is this "too chilled"?
