Been there once, I loved it. Beautiful city to wander around. It might be harder for you since you have 2 kids. I just went all over the place and did not get lost one time. It's very easy imo. If you plan on going against the Yankees, keep a lookout on the Red Sox site to enter a raffle. Since Yankees games are popular, those that are chosen get to buy first. I sat in RF about 2 rows from the field. Paid about 60 bucks and I loved it. Here's a link for the Subway to get around http://www.mbta.com/schedules_and_maps/subway/ It's easier to get off of Kenmore than Fenway, don't make the same mistake I did lol. You get off and basically keep walking straight on I think it's called brookline ave. You'll pass cask n flagon and boom there's Fenway. Make sure you take a picture of the 2013 WS banner! Hope you have fun!
