Yup, I usually stay at one of the two Hiltons connected to the terminal. No desire dealing with a shuttle bus (even if operated professionally) if I an avoid it.

I would consider submit a summary of the incident to Hyatt Corporate. Not to ask for compensation, but to make them aware that the service their property is relying on and is advertising on their website (presumably) is using completely unqualified employees that effectively put their guests at health and property at risk.
