This hints at what is likely the real reason why these rooms are often not shown for sale online - the property's desire to have maximum opacity and flexibility in pricing. That gives them a lot of leeway to price the room to the customer. For a wedding party spending tens of thousands already, maybe it's thrown in as an extra. For a celebrity on the night of a big event, maybe it's $10k/night. And for the right elite, maybe it's a very nice, very lucky upgrade.
