He said Greenbrier management, which contracts with the companies for the bus tours, immediately ordered them to stop advertising the tours as casino trips.
"The important thing here is we want to protect the integrity of The Greenbrier, and the state of West Virginia," said Puccio, state Democratic Party chairman and former chief of staff under then-Gov. Joe Manchin.
"The issue is this, this commission does not govern what the hotel does. You govern who comes into the casino," said Lottery Director John Musgrave.
He said the Lottery has treated the casino day-trips as events under the old rule, since the packages generally include a buffet lunch or brunch at the hotel.
"If they do that 365 days a year, is that an event?" Musgrave said. "When does it cease to be an event and become a routine thing?"
Afterward, Musgrave said he believes the new definition is consistent with the legislative intent under The Greenbrier casino law, which states the casino is to be an amenity "that is increasingly important to many actual and potential resort hotel patrons."
He also said the commission's interpretation that the 400-room occupancy requirement applies to overall occupancy at the resort - not to rooms booked for the particular event -- is also consistent with the legislative intent.
"We've always interpreted it that it was overall occupancy," he said.
Musgrave said he believes the new rule provides clarity, both for Greenbrier management and for Lottery regulators.
Meanwhile, revenue for The Greenbrier casino continued a sharp upturn in October, according to Lottery figures.
