In five years, Marriott International will double its hotel footprint in the Middle East.

Six new properties have been added to Marriott International’s pipeline of 37 previously announced hotels in the Middle East and Africa. They stand for three of Marriott’s lodging brands that cater to travelers seeking luxury, upper-moderate price points, and extended stays.

Included is the first extended-stay Residence Inn by Marriott property in the Middle East, which opens in a Bahraini suburb of Manama later this year. Marriott International will provide customers in the Middle East & Africa with 74 hotels and resorts and more than 17,600 rooms across seven lodging brands once all 43 of the hotels currently under development or construction open by 2016.

According to Ed Fuller, president & managing director for international lodging, “our development opportunities in the region remain strong despite recent economic and political uncertainties in the Middle East and the northern tier of Africa.” “The World Travel & Tourism Council predicts that by 2016, nearly 90 million tourists will visit the area annually, and these new hotels, which are anticipated to open over the following five years, will be in a prime position to assist in accommodating them. Today, the Middle East receives 68 million tourists annually.”

According to Mr. Fuller, Marriott continues to actively look for lucrative expansion opportunities in sub-Saharan Africa and anticipates announcing projects in nations like South Africa, Mauritius, Tanzania, Angola, Nigeria, and Benin later this year. He added that Marriott’s first two projects in sub-Saharan Africa are anticipated to open in Accra and Kigali next year. “The region has enormous tourism potential, and we plan to play an important role in its development,” he said.
