More than a decade after closing the old PineIsle Resort, Lanier Islands resort in South Hall County is trying to get a feel for development possibilities on the now-vacant property. “We have our own speculation, but we recognize that it’s an excellent site to develop and we’re just trying to understand the opportunities for what and … when,” said Bill Donohue, executive director of the Lake Lanier Islands Development Authority. The authority and Lake Lanier Islands Management, which operates the resort, are looking to hire an outside firm to give them a fresh take on the matter.
