At Megacorp, they give us 28 days of PTO... The amazing thing is that no one takes the time and so most of my office will be out for a good part of December because we have use it or lose it.
Im in the same boat. This is precisely why I am SURE to take my time off before November.
I telecommute from home, so the end of the year is like a second vacation for me -- real calm and restful.
