Charleston County hotel owners sold about 24,200 more room nights in September over the same month a year ago, boosting occupancy by 5.6 percent.

“September was an extremely good month for Charleston County hotels as occupancy, average daily rate and revenue per available room all increased,” said Perrin Lawson, deputy director of Charleston Area Convention and Visitors Bureau.

The county’s hotel occupancy rate climbed to 73.5 percent while the average daily rate jumped 5.2 percent to $129.11 and revenue per available room soared 11.3 percent to $95.27.

All four of Charleston County’s submarkets performed well, with North Charleston reporting the largest percentage gain in both occupancy and revenue per available room. The other submarkets are the Charleston peninsula, East Cooper and West Ashley.

For the year, the county is up 0.6 percent in occupancy.
