Hi, we were there from 2/13 - 2/17. We spent 2/17 at the MK and it was HORRIBLE crowded. Space mountain had a 70 minute wait, Buzz 45, there were even lines for the TTA!!! It was fairly crowded from 2/14 on and kept getting worse the closer it came to President's weekend. I LOVE WDW, but was actually comfortable with the idea that we were leaving.
I was there last year from 2/4 - 2/8 and it was WONDERFUL!! I think the farther in to Feb that you go the more crowded it gets.
You might hear differently, but where we were it was mobbled with people and not much fun.
