Fenway is the oldest park in MLB and has been the home of the Boston Red Sox since 1913. Fenway has hosted the World Series ten times and the Red Sox have won five of them, most recently in 2013 when I was living here!
The Boston Red Sox will play two baseball games against the San Francisco Giants during the 2016 IEEE PES General Meeting. The games will be on Tuesday and Wednesday, July 19 and 20. The Red Sox will also host the Minnesota Twins on Thursday to Sunday, July 21-24. All of these games except for the Sunday game will start at 7:10 PM at Fenway Park, which is a 15-minute walk from the Sheraton Boston Hotel. Tickets will be on sale at http://www.redsox.com
If you do not want to go to a game but still want to see Fenway they do offer tours for 18$ every day. You can buy tickets at http://boston.redsox.mlb.com/bos/ballpark/tour.jsp
