What's "very long"?
I just keep hiring students at my work to poorly replace me. The urgent things can scrape by, but other things fall off their desks and I look like a God when I return and clean up the messes 
But seriously, I worked for 6 years before my first week off, and it was great. I have 2 2-week vacations book for 2010 (and Feb of 2011), which is more than I've ever taken off in a year, before. I get 4 weeks and 2 days of paid vacation a year, plus whatever I bank through overtime.
Now if by "big", you mean "2 months", man, I wish I could do that, too. Hoping do to leave with income averaging in a couple years
