Dont you think bachelors have girlfrends in QR ? So see 4 girlfrends 4 bedroom !
Or he might want to rent it out or share it with 4 other familly member .
Or maybe he need 2 rooms for all the money he is saving in QR becouse he is single and dont have to spend on wife and her inportant staff.
In Doha and QR there is a lot of single people if you dont make same conditions as other why would they stay when other airlines gives same conditions . Remember Qatar has money so you want to save on fuel and bechelors and water and paper ?? he he he
Any airline started to save money in extreme got crash !
