& I finally got a chance to go to Guest services to ask about taking construction photos. They told me you can take pictures of anything you want as long as your in a guest area, & not in an employees only area, construction area, climbing on walls, trash cans, barriers, benches etc. So if your doing anything unsafe to yourself or others or any of the above to get pictures, than yeah, they can tell you to stop/delete pics/leave etc. But basically as long as both feet are on the gound & in/on a guest area/pathway, you are good. So if approached by security, than very respectively tell them what guest services said, along with pointing out that there is no published policy saying what you can/cant take pictures of.
