Rumors were flying out on Kiawah Island this week about visiting celebrities, but a shroud of official secrecy kept their identities private.

The gossip flowed through back channels by way of a source who contacted The Post and Courier but would not go on the record.

The anonymous tipster said Bill Gates, chairman of Microsoft, had rented out the Sanctuary, a resort where rooms go for as much as $1,000 per night.

Kiawah spokesman Mike Vegis said he could neither confirm nor deny the report.

“We never give information on our guests,” he said.

The Bill Gates Foundation was contacted Wednesday and Friday but provided no response. Town Hall and Kiawah Community Association staffers said they had no information on the event.

Citing an unidentified source, WCBD-TV reported Friday that it had confirmed the celebrity crowd included Gates, Warren Buffett, Jeb Bush and Dan Gilbert, owner of the Cleveland Cavaliers.

Vegis had no response to the report.

What’s known for sure is that the Sanctuary was closed to the public for a few days, but was scheduled to reopen Friday afternoon. And there were a passel of private jets and limos at Charleston Executive Airport. People working at the airport, though, said they couldn’t talk about the comings and goings there.
