My understanding is that the hall-effect sensors usually work in tandem with other occupancy sensors to lower HVAC bills, like: http://axxind.com/hospitality/guestpresence/ .

I think the hall effect sensor functions as a "latch" to prevent the motion system from turning off the HVAC if you are in another room of a suite, out of view of the motion sensor, or asleep.

This is correct. In addition to working in a hotel for ten years, I was also there when it was gutted and renovated and the system installed. While some hotels may track this stuff beyond just a simple occupancy flag for HVAC (e.g., Las Vegas), the vast majority don’t have the interest or capability to.
