I've never really understood the deployment time. Couldn't you just remove the entire crew and slap another crew in their place? 6 year on, 6 year off? But I guess that wouldn't be very narrative like.
I'd rather see a global crew fatigue level, with crew shortages putting more pressure on already worked crews. Crew deployment would then only really come into effect during deep space exploration, through budget cuts on manpower, or from long deployment due to war.
As for the OP, TNG had Pajamas for uniforms, had the ship's shrink sit right next to the captain, and had a kid drive. They also had handguns which could disintegrate people worn on the hip, with no trigger guards. In Aurora, maybe the kids should be left on the Orbital Habitats.
Or have something you could research that allowed for crew to relax faster...
