I flew from South Africa to the Middle East via Addis. Upon my arrival on Saturday evening just after 9 most of my fellow airplane passengers ran to the "next" destination - the hotel voucher transit booth. When I got there I understood why the other ran! One big "Q" with only two staff issuing vouchers. I finally got my voucher and proceeded to the immigration booth - only one for all transit visitors although all the other booths' Qs was rather empty... Finally got through and waited for the bus - it was now already past midnight!!! And we had to get the bus the next morning at 06:30! Not much sleep left. The airport itself was clean.
