This year, I figured the same thing would probably happen, so I planned at the beginning of the year to take those two weeks for vacation. Earlier today, my thinking was confirmed... we're doing the exact same thing this year. Seems a shame to waste the vacation time that I could spend some of in other ways at other times, but at least I'm not having to scrape together this year to avoid unpaid days. That, I feel good about.
Another nice thing, recently, is that things have calmed down here at work. I'm no longer fighting fires every other day, and not being asked to do 4-5 things at once. This is a good thing, since I've got a couple big projects coming up that I could use all the time I could get to do. Of course, now that I say that, guess what's going to happen? :-)
