Question about hazing in the United States Marine Corps, and boot camp?

I have two questions, the first one is about hazing, I know its a movie, but do things like being forced to get branded (like in Jarhead) really happen in the Corps? How bad is the hazing? My second question is kind of stupid haha, but when in boot camp, and nature calls, more specifically #2....how much time do you get to use the restrooms? Without getting to graphic, I tend to take a while dropping the kids off at the pool, will this be a problem? Thanks
