which seems like the hotel is cutting off its own nose
(#) notnsure of the industry term but you get the idea
The only thing they might engage in is opaque pricing, which is Priceline and hotwire auction. But that is different since it's not a publicly advertised price, the buyer puts in how much they want to pay and they are stuck with whatever hotel Priceline or hotwire give them.
But reputable hotels don't resort to that since that attracts price sensitive guests that aren't desirable anyway, such as prostitutes and drug dealers.
Maybe at the 1 or 2 star level, but every other hotel on the planet secretly loves the price discrimination that Priceline and Hotwire offer.
You won't see a $1400/night boutique hotel on there, but a $300/night place will offload for half the price if they're relatively unbooked.
You can also contact a hotel directly and say you're thinking about reserving on so and so website (aka travel agent), and if you reserve directly, they might give you a discount for not having to pay commission.
