Luckily we visited Blarney in the dead of the winter, because I could not imagine the long lines weaving through the old castle.  My mind would get the best of me somewhere near the dungeon while waiting in standstill, no place to move in any direction, and I'd jump the moat and run for the hills.  As far as kissing the Blarney Stone, I passed because of rumors of what the local college kids do.  I leave that to your imagination.
