CHARLOTTE, N.C. (AP) — An analysis of sales tax data shows the 2012 Democratic National Convention in Charlotte packed local hotels, but appears to have had limited economic impact for the city as a whole.

Demand from the convention allowed hotel managers to charge two or three times their usual rate during the normally slow Labor Day week. Restaurants and bars also posted strong sales.

However, the data showed the four-day DNC didn’t dramatically boost retail spending. Tax receipts for businesses other than hotels, restaurants and bars increased by 2 percent in September, compared with 2011.
