This tour uses of a floorplan for navigation, including a field of view indicator show where you are looking. This is a big help putting each virtual tour node (viewpoint) into context with the surroundings and with other nodes.
Before viewing the VR tour, check out the still image gallery. Then compare the difference in experience between the two. View the still images first, because once you view 360s, you get a spacial context for the still images you wouldn't otherwise have.
