The Karwa bus service is much better than the taxi. 3 years now and never been late for work except in fog. If you ever need a regular taxi again, I have the number of a brilliant self employed limo driver who has been in business here for 16 years, totally reliable and knows every back road shortcut. He is actually cheaper for me to get to Dukhan by 50QR than Karwa! Let me know if you need the number. JJ
