i had a 16 hrs transit in baharain when i went to nepal couple of months ago.. but i was traveling through frankfurt- baharain - ktm... however they did provided me with free hotel facility which included dinner and breakfast...there is a customer service counter which looks after this issue... you'll find it as soon as you enter the airport... or ask someone for it they'll tell you...and you might find few nepalese at the airport too... i found 2 nepalese and we stayed together... have a safe journey...
