We learned after 9/11 and great recession that it takes too long to get your average rate/revpar back up if you deep discount. As others pointed out, there is only so much business out there.
Omni hotels is shutting down all but about 15 hotels through May. Here in Austin, the JW, Driskill, Line and others have already closed.
We've had 10-15 guests a night, regardless of pricing. Half of that is from an airline crew.
Not to say that you wont find deals, just depends on the operator/owner. Opaque websites are your best bet, like Hotwire. We can deep discount there without the rest of the public or competition knowing.
