Acrobatics(3/26/10)
Q: If a character fails an Acrobatics (tumble) check when attempting to move through an opponents square, are they stopped, or do they get through and suffer an AoO?
A: (James Jacobs 3/26/10) If you fail an Acrobatics check to move through an opponent's square, you stop in the square you were left to make the attempt to go through that creature's square and your movement for that turn ends. If that square is occupied (say, you ran through three wererats in a narrow tunnel only to fail on the fourth), you fall prone in that square. If you have any more move actions left in a turn, you could try again, of course.
You can see that (and much more info) here.
