My mistake. I confused it with "SimpleJoys" which they're using all over their website. SimpleJoys oddly enough can only be downloaded from the official Hilton Dropbox account.

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.
