The Macon Centreplex increased its revenue and decreased its net operating loss over the past three years, according to Marriott Hotel General Manager David McCartney.
Three years ago, the city of Macon awarded the Noble Company the contract to build the Marriott Hotel and manage the Macon Centreplex.
The city also leases the convention center.
McCartney says the financial numbers prove that the decision was a step in the right direction.
"I think it's a combination of reasons for the increased sales," says McCartney.
He says a slight upswing in the economy, an aggressive marketing campaign and the power of the Marriott brand has helped bolster sales.
According to his presentation to city council Tuesday night, the Coliseum and the Macon City Auditorium brought in $1,470,504 in fiscal year 2009.
In 2011, they brought in $1,966,032, an increase of almost half a million dollars.
