Interesting report, thanks for the details of transport into Doha from the airport during a layover. I will be trying the Doha stopover in a few weeks.
The bus from the city looks useful; did you happen to find out how late it runs? I am aiming to go back to the airport at sometime around 22:00 or 23:00, with an 02:something departure I don't need to rush but I want some lounge time
I'm happy to use an efficient bus.
