The Universal-Loews partnership is a Joint Venture, which is rare in the theme park world. In a typical "land-lease" deal (like Disney's with the Swan & Dolphin), one company owns the land and another just pays rent to run a hotel on it.
Universal and Loews, however, are legally and financially "married" through a company called Universal City Development Partners, Ltd. Lowes and Universal directly share the profits made thru the hotel so any changes to the hotel is also going to hurt Universal. Any downturn in pricing or revenue hits Universal directly in the wallet.
This is not like Disney with swan/dolphin, if people stop going to those hotels it's irrelevant to Disney there still going to get there lease money.
