To fly or not to fly... That is the question

I'm homesick. Really, REALLY homesick. I'm trying to decide if taking a 10 hour flight with just me and the kids is feasible. I know I can keep dd occupied and ds should sleep most of the time. But what do I do when I need to pee? Surely all three of us can't fit in a teeny airplane bathroom.

*sigh*

I really can't decide...
