Duqm, Oman\'s new city on the Arabian Sea, will see the opening of three hotels with a total of 391 rooms, said a statement issued on Tuesday. Maitha Al Mahrouqi, Undersecretary of the Ministry of Tourism said: \"Oman is seeing strong investor demand in the sector, especially in niche properties. \"This is from government sponsored joint ventures through OMRAN and increasing Omani participation.
