My son and I are visiting Boston soon. We have tickets to a game and would like to take the Fenway Park tour the next day. It looks like you cannot buy them in advance. It says the first tour is at 9 and it is first come, first serve. Any suggestions as to what time we should arrive to try to get a tour ticket for sometime that day? Also, we are attending a night game. What kind of pregame activities can we expect?
