My Bags are Finally Packed

I'm trying to decide if I should stay up or go to bed and sleep 4 hours. Considering I will be on a plane for 12 hours, I think I can catch a little nap or 2. I am SO NOT A MORNING person, so I am afraid if I go to sleep I will be late. So what am I doing now? Checking the updates on the volcano every 5 mins. It appears to be acting up again and holding out steady for a few days:( Please pray it doesn't blow tomorrow and I get stranded at an airport somewhere. I am SOOOOO afraid of this!
