Seriously Hotels.com?

I’m looking for a hotel room for the last two days of the PubCon conference in Las Vegas next week and this is the search results I got back from Hotels.com – $5,449 per night at Caesars??   The whole point of using a site like Hotels.com or Travelocity is to find cheaper & discounted rates.  I would think they’d have a rule in their search algo to never show prices above a certain level – say $1,000 per night – as it just looks ridiculous and not a usable search result for a user.  Hello?
