If there's one problem with going on vacation it's that it's expensive. Really expensive. Sure, you can save your pennies and whatnot but everyday life costs more than you would expect and can often cut into your fun money.
At this point I think I've considered cancelling my vacation plans three times since I've made them. But even with my worrying I should be fine on my upcoming trip. I simply need not buy anything and quit eating until 2012. Luckily there's a creek near my place so I can go down there to wash my clothes. I just need to find a rock to beat the laundry against and I'm good to go.
