Jazz Fest and Jazz Hands

is it sacrilegious if I opt to shower during my Jazz Fest trip when the students are having their worship time? It's the only time I can think of when I won't be trapped with the 20 7th/8th grade girls fighting over the one shower and one outlet. 

I need to maintain some level of secrecy about how I get looking so fine. The students need to see the finished product, NOT what it takes to get there. If they saw my crazy lion mane hair before it's straightened, they might not respect me anymore. I gotta keep that respect when most of them are taller than me to begin with!
