Every event as different and has their own specifications as far as whether or not they allow 2 hours or visuals of the back stage typically it will be included with a VIP package and efforts not offered than that is not something you can do
Each event sets up their own stage so you have to have a pass for each event if they have offered
Unless you have some form of credential everything "back stage" or "behind the scenes" is off limits.
If you have a backstage pass probably.
