Marriott International cashed in up to $475 million in adjusted net income last year, up 23 percent on the prior year.

The increase comes despite a tough global economy, the hotel group's EBITDA totalling up to $992 million in 2011, up 12 percent on the $855 million in 2010.

Excluding the Middle East and Japan, the company saw its profits rise worldwide with international REVPAR increasing 6.3 percent on 2010 while North American experienced a 6.5 percent increase.

Looking ahead, the hotel group expects 2012 to bring in five to seven percent more REVPAR in North America and worldwide and is expecting to fill up to 30,000 rooms over the year.

“For 2012, assuming a strong U.S. dollar and modest fee revenue growth in hotels in Washington, DC, the company expects full year fee revenue could total $1,410 million to $1,450 million, growth of 8 to 11 percent over 2011 adjusted total fee revenue,” the company said.
