Saints fans near SEATTLE WA....

Last year I went to the Seahawks/Rams game and I parked in the stadium parking lot. It was expensive but I got to the game many hours before kickoff and drove right in and got a decent spot and didn't have any problems getting out (although I was heading south on I-5 to Portland and I guess most everyone was going north.
I had looked into some kind of shuttle service but could not find anything convenient; not sure what I'll do for the Saints game but I'll be there early for the tailgate.
