CANYONVILLE — With business booming and waiting lists getting longer, the Seven Feathers Hotel and Casino Resort is undergoing a major expansion estimated to cost about $40 million.

Expected to be complete by March 2009, the Canyonville entertainment center will feature 154 new hotel rooms, a day spa and a 250-seat buffet.

The hotel has been operating in excess of 90 percent the past five years, according to Bruce Schoneboom, general manager of Seven Feathers.

He said the expansion was spawned by waits in the 24-hour restaurant and that the hotel turns away 1,200 reservation requests per month.

At a groundbreaking ceremony Thursday, Sue Shaffer, chairman of the Cow Creek Band of Umpqua Tribe of Indians, said not only will the expansion contribute to building Seven Feathers as a premier destination resort, but the project will also furnish more than 100 jobs.

Travis Hill, director of hospitality operations for the Umpqua Indian Development Corporation, said the hotel suites, which will cost patrons $175 to $225 per night, will be 600 square feet and will each feature two 42-inch plasma TVs, a wet bar, minibar and jetted hot tubs.

Hill said the planned River Rock Spa will offeri manicures, pedicures, body wraps, massages and facials. A wet and dry sauna, a soaking tub with a rain shower and a sunless spray tanning booth top off the creature comforts.

Guests will be welcome to sip champagne in terry cloth robes while they are pampered.

The Gathering Place, a 250-seat buffet restaurant, completes the expansion with choices of Spanish, Italian, American and Asian food. The restaurant is scheduled to open in November.

Other aspects of the expansion include two outdoor courtyards, an expanded video arcade, increased housekeeping facilities and a glass walkway connecting the hotel to the gaming floor.

Between the new hotel, meeting rooms and larger restaurant, the whole complex will be almost a third larger, making Seven Feathers Resort over 360,000 square feet.
