The shuttles were a joke - they drove you about halfway there - past all the cool stuff and the Tennis center - and then you had to walk up 2 flights of stairs to the Long Island Railroad station, across a boardwalk about the length of a football field, back down 2 flights of stairs, through the subway terminal, back up and down another flight of stairs and then you were at Citi Field. And it was $22.50 to park there!!! I need to map it later - it was ridiculous. Luckily our seats were insane so we really didn't care. And we walked the whole way back and it was a really cool walk - I've never been there before and really enjoyed it.
