The Denver Post: The city may own the massive glass-winged hotel built next to the terminal at Denver International Airport, but local officials still don’t know for sure how much money its operator is making.

That is the gist of a letter sent Monday by Denver Auditor Tim O’Brien to Mayor Michael Hancock asking that city attorneys “take action to require the Westin to comply with Denver law and the terms of its lease.” O’Brien alleges that Westin, a hotel brand owned by Marriott International, has breached its contract with DIA by failing to provide key information sought by auditors.

“If I can’t see this important information,” O’Brien said in a statement, “I am certain the airport is also not monitoring the money as it should. That’s a problem for all taxpayers who care about the asset they helped pay to build.”
