I just tried to look for backups in terms of transportation and found this.

The Greyhound bus is having a NYC sale $15 each way, $30 roundtrip
(no tax) from Port Authority Station to Boston, MASS

1. Port Authority, NYC to Boston, MASS ~ bus arrives at South Station.

2. Take MBTA subway: RED line - SOUTH STATION and go one stop to Downtown Crossing and transfer to the ORANGE line and go 3 stops to NORTH STATION

~ Find signs that take you to the Fitcburg/South Acton Line - Commuter Rail

3. From North Station take it to South Acton Station (11 stops)

~ According to the official hotel - Holiday Inn, they have shuttle services that can pick you up from South Acton Station to the hotel. Times for complimetary shuttle service is 7am to 10pm

first link is to the Greyhound Bus NYC fare/schedule information
second link is the MBTA maps/schedule - subway and commuter rail

Hope this helps for any NYC/NJ area competitors who are planning on taking public transportation.

Just an FYI, though! The MBTA isn't a ton of good if you're going as far out as Acton is, Acton is probably a good 45 minutes outside of the city. Going all that way on the MBTA with all your luggage is going to take a while, plus probably be pretty cumbersome lugging your stuff around. It's do-able, but if you're going to do this, pack light to save yourself some hassles! Granted, Tim's directions are easier than if you're going to try the T from Logan, which I also don't reccomend.

Also, anyone coming from NYC that isn't driving, please DO NOT take the Fung Wah bus! They've been involved in several accidents lately and aren't safe, IMO.
