Hotel
If you're looking to explore Boston a bit this is a great place to stay and not too expensive either. This is about 45 minutes to a half hour away from the venue.
Hotel
This is a mile away from the venue and is very affordable.
Train
This train goes from North Station in Boston to Haverhill station. It is about an hour ride and the Haverhill stop is just an 8 minute ride to the venue -- affordable too if you don't want to spend a lot on a rental!
