Kalispel Tribe officials have unveiled the River Tower addition of 192 luxury hotel rooms to Northern Quest Resort & Casino in Airway Heights.

With a total 442 rooms once the River Tower opens to the public May 1, the venue has grown to become the largest casino resort in Washington state, tribal officials say.

“We just want to keep evolving,” said Phil Haugen, CEO of the Kalispel Tribe Economic Authority. “We are proud of being something that attracts people to this community.”
