If it was just for you, it would have been easy. Looking for 3-4 will be very difficult, especially if you want to sit together. I'm from Miami but I went to Fenway last month for the first time. I took the T everyday and from Kenmore all the way to Gate A, I was asked at least 30 times if I need a ticket. I went to 3 games and it was like that everyday, so try that area. Although it was against the Yankees, so that might have something to do with it. I know it's not much info, just trying to help out. Good luck finding a ticket!
