You can also consider Amwaj Islands (8 km. from the airport) or Budaya
Budaiya for a Pilot!! Its a no-no. What will happen if you have early flight on week day???? Driving from Budaiya to the airport between these times 07:00 AM to 10:30 AM is terrifying, and the traffic is soooo bad, I really suggest to take bicycle if you intend to go to Budaiya, you'll reach your plane much faster!!
