Camping trip with four mates and one shower block

Going away for a week with friends. Campsite, shared shower block, tents about two metres apart, the lot.

I am not worried about anyone seeing anything, because I am not planning to wander about undressed. What I cannot work out is the routine. At home it is five minutes in my own bathroom and nobody knows anything. There, everything happens in a communal block at whatever time the queue allows.

Has anyone done a full week somewhere like this? Is there a trick or do people simply pause for the week?
