The largest cruise ships plying the seas, the Oasis class that can carry up to 8,400 passengers and crew and is run by Royal Caribbean Lines, will never call on Charleston.

That was the guarantee offered by the keynote speakers in a three-day symposium that began in Charleston Wednesday night. The approximately 150 attendees offered up some soft applause at the news.

The conference was organized by local preservationists, the National Trust for Historic Preservation and the World Monuments Fund to try to help Charleston and other historic port cities balance cruise ship tourism with the cities’ quality of life.

Craig Milan, a former Royal Caribbean executive who has spent 12 years in the cruise industry, offered some consolation to those concerned about cruise ships’ growing presence here. “I can assure you the Oasis of the Sea will never be in Charleston,” he said. “There’s just not the market for that ship.”

The conference will wrap up by 12:30 p.m. Friday.
