According to research this used to be Days Inn Main-gate West, and was also (I heard)used as housing for Splendid China *closed/abandoned* employees (who came from china to work there, you can see a bridge linking Splendid China to the hotel in the back) . However it is now closed but seems to be a base for Splendid China security and since Splendid China has a $500 fine for trespassing, I'm sure this does too.
Going on internet archive site here is some information I got about the hotel from Splendid China's webpage
