Long stopovers both ways in DOH - 5.5 and 4.5 hours. Limited choice and low quality of food and drink if you have no lounge access. Childrens play area was closed and looked in a bad state of repair. Toilets in sufficient supply but not very inviting. Boarding announcements nonstop and very loud - airport was cold buses were even colder. Bus ride and waiting time at the aircraft was unbearable on both trips. On the return leg we remained 35 minutes in front of the aircraft before being allowed onboard. As a result we saw the baggage handlers for our flight throwing violently all suitcases on the tarmac prior to loading - not what you would expect. Transfer and security were efficient. If you have a short transfer in DOH it may be okay. For longer stopovers wait until the airport has been re-vamped or take warm clothing and aspirins.
