Replying to Graduating College Early?

Has anyone here done it? Pros? Cons?

Most of what I've read is from people who plan from day 1 of college to graduate early, and that sounds miserable. However, it just kind of worked out that I could graduate a semester early.

Basically my two options are:

1. graduate early - 18 credits this spring. 19 next fall. save money. ski and travel for a few months. start job early.

2. graduate on time - 15 credits this spring. 14 next fall. 8 next spring. start job on time.

I realize there's probably stuff I haven't thought about though. If you have done it, how did it work out for you? Would you do it again? Anything I should know?
