Since I'm not the one driving, I can nap both to, and from, there, meaning no risk of an accident from exhaustion or the like. I get to sleep, rather than being forced awake.
It has many disadvantages. I must leave when they leave, be ready when they're ready, if I forget something I'm out of luck, and mainly, I'm stuck there all day. As in, dropped off at seven AM, picked up at 7:30 PM, stuck there all day. With nothing to do but work, and then tae kwon do after work.
That being said, I think I'll be fine. I'll manage to keep myself busy enough.
