It is pretty easy..... unless there is also a Senators game. Friday June 6th is the game at home vs. the Kickers. I assume you are coming to that game right? That is the game there is also a Senators game. It isn't really all that bad, you just need to try and get there a bit earlier. Plus, I think a parking charge is needed to get in for the baseball game but not the soccer game so.... you need a parking pass issued by the cityislanders. I have one you can use.
I should be able to help you out. Check your PM inbox for my email and get in touch (either by email or this thread). I have a parking pass you can use. I also may have 2 extra tickets you can use.
