Charlotte tourism officials are asking lawmakers to reconsider their latest plan to help the Carolina Panthers, saying the proposal wouldn’t leave enough money for the Charlotte Convention Center. A bi-partisan bill introduced last week would allow the city of Charlotte to use existing taxes to help pay for renovations of Bank of America Stadium. The bill was offered as an alternative to the city’s original request to double the local prepared food tax to 2 percent to raise $144 million for the stadium upgrade. The bill would instead let the city use existing local taxes earmarked for the convention center. “The bill directly and negatively impacts one of the city’s leading sources of tourism for the region, the Charlotte Convention Center,” Tom Murray, CEO of the Charlotte Regional Visitors Authority and three other tourism officials wrote to the bill’s four sponsors. “While we support he Carolina Panthers, our primary concern is to preserve the city’s investment in the Charlotte Convention Center and support the tourism industry.”
