Heading from Austria all the way to Istanbul. Stops are planned in Sighisoara (1 night), Sibiu (1 night), Brasov (3) nights, Chisinau (2 nights) Bukarest (2 n.), Warna (2/3 nights, Sofia (2/3 nights), maybe plovdiv, Istanbul (2 nights). Are 80 hours spent in trains across 3 weeks too much (75 % of that will be spent in sleepers where we plan to either get a couchette or 2 bed compartmemt)? Is it too much time in trains?

Any considerations for alternative stops and activities are welcome but we are mostly set on route.
