Flight
This is the best place to fly into. You could go to Providence (1 hr drive) or Boston (2 hr drive) if it is easier for you to get there.
Hotel
This is a close hotel option to the venue.
House Or Rental
The wedding will be in Salem, CT - but there are some amazing airbnb options around the area. For some perspective: Glastonbury, CT is about half an hour from Salem; Mystic, CT is on the shore and is about 35 minutes from Salem.
