It all depends on how organizers plan their events. There is always a way to come up with roles for people who don't have the stamina to be on their feet entire weekend, people who can't run and gun non stop. Everyone is different. Some people have hard time staying awake at night just because they are wired that way, some people can't stay up for more than 15-16 hours etc. but if things are organized in the right fashion, there will be something to do for everyone.
