The closest airport to the venue is Portland International Jetport (PWM). Make sure you pick the Portland airport in Maine, not Oregon!
Alternatives would be Manchester, NH or Boston Logan Airport.
You will need a car to get to the venue. In the interests of the parking situation, we encourage carpooling.
There are a few options, as Maine is a tourist destination. There are fewer options, because it's in the shoulder season.
Damariscotta and the Pemaquid Peninsula are home to many great B&Bs. We recommend The Newcastle Inn, The Mill Pond Inn, or The Cod Cove Inn.
Hotels from major chains in Bath, ME or Brunswick, ME would also suit, for those who don't mind driving an additional half hour through coastal Maine.
Lastly, Midcoast Maine is positively loaded with short-stay apartment rentals like AirBnB or VRBO. Start by searching "Damariscotta" or "Jefferson" to get in the right area.
