Problem with Disgaea 3

Sometimes, I have to wake up at 5 am to take someone to work.
I usually go back to bed, seeing how I have to go to work myself at around 10 am.

With Disgaea 3, this poses a problem.
Do I take a few hours to level up a little before work?
Or do I just go ahead and take a nap?

Man, those trips to Class World seem really tempting right now. I need to reincarnate all of my characters, boost their mana... mmmm, leveling...

N-No! Resist!

Character Levels range from 35~15. Aha... see?! Leveling would be a great idea right now-! Who needs three hours of sleep, right?
