I'm going to Europe for a month. I am planning to go to 8 cities. Is 5 days too long to stay in Paris? Should I cut it down to 4 days?

Thanks
;)

I think 4 days is enough to do a whirlwind tour and hit the main sites.

Yup, 4 days is good for a whirlwind, but personally, I'd go with 5. I took a full week there and saw *almost* everything, but also had a chance to kick back and relax. Still wish I had more time, though... I dunno, I always try to give each city 5 days if I can! (If it sucks, you can leave early...)
