Charleston County hotels sold 11,400 more room nights in May over the same month a year ago, boosting occupancy by 1.3 percent.

Hotel occupancy stood at a healthy 77.5 percent in May, according to the College of Charleston’s Office of Tourism Analysis.

Also, hotels saw a 2.8 percent increase in the average daily rate to $140.37 and a 4.2 percent boost in revenue per available room to $108.86.

For the year, occupancy is down 1.0 percent, mainly because about 300 more rooms are available than there were a year ago with the addition of new hotels in the metro Charleston area.
