没有听到过有这样的活动， 你可一式式去MITBBS的BOSTON 班上发个贴子， 那上面有很多人看的。(看到你以经发了， 嘻嘻)
去MANSION自己开去就好了， 你可以提前去AAA 买好门票/套票， 或者直接去门口买。

中国城有几家TRAVEL AGENCY， 我得帮你找找网站去。

do you just mean 华人旅行社? I think there're some in chinatown. You can look at the directory on this websit http://www.sinoboston.com/modules/xdirectory/ ,
or, if you don't mind if they speak chinese or not, you can just take the greyhound from the south station, and I guess you can also buy the ticket to the mansion right there at the station.

thanks so so much!!!
