I try to give FE the most privileges because they work so hard loading the trailer, pushing, etc.
Eat first, first to get seconds, first choice of bud seat, etc.
Fortunately some of ours are also wind players so they will play piccolo etc in the bleachers.
Iíve also seen some schools let them play their xylo or marimba on the track for stand tunes. Nothing wrong with that at all if it will work for your school.
Not sure if this helps much but good luck!
