Allow at least 90 minutes here on any DOH connection. The a la carte dining alone justifies an earlier arrival.
Al Mourjan Business Lounge spans two levels in Hamad International's southern concourse — roughly the size of a small shopping mall. Multiple full-service restaurants replace the typical buffet: one focused on Arabic mezze, another on international mains, and a dedicated dessert bar.
I ordered shish taouk and a mezze platter from the à la carte menu during a three-hour connection. Quality matched a decent city restaurant, not lounge food. The spa offers 25-minute neck-and-shoulder treatments that can be booked at the reception desk on arrival.
Quiet rooms with lie-flat beds are available for longer connections — reserve early during peak banks. The walk from some A and B gates can exceed 15 minutes, so check your departure gate before settling in for a long meal.
Business class passengers on Qatar metal get complimentary access. Oneworld Emerald and Sapphire members can also enter on qualifying itineraries. If you are connecting through DOH on Qatar business class, this lounge is reason enough to prefer Hamad over competing Gulf hubs.
