YES! The Ghan was definitely worth the money!
Great scenery, friendly & helpful staff, and
Small but perfectly formed cabin with en suite (for doubles). Bunk beds, so no chance of hanky panky. ESPECIALLY the panky!
Only stayed overnight in Darwin β 2130hrs: 35deg & 60% humidity!
Flew back to Adelaide, drove to Lyndoch in the Barossa Valley for a birthday
Then flew back to Melbourne for the drive home.
