I took my extra equipment to a recent Graduation session at University of South Florida. I always advise that graduates take their photos early before the day of graduation.
Graduation day is typically the busiest day that you can take photos as people are there with their families and often can be seen in the background of your phtoos. Sometimes they are easily removed sometimes they are not. For video, they are definitely not removable.
If you want to maximize your experience, get them done as early as possible or try an off campus site.
