I'd actually be moderately surprised if there were no extant hotel companies that have commissioned a typeface. They might not have bragged about it, and you might not have heard about it, but it's not like it's an unthinkable thing to do.
Can you provide a source that Hilton commissioned it?
Edit: In a bit of an ancillary note, it looks like they are serving the font directly from their wp-content folder as a static asset. This might indicate that they either came to own it or commissioned it.
