Of course you'll have to make sure to visit the beach at some point during your time in Maine!
Check out the downtown area of Portsmouth. So many cute bars and restaurants to choose from!
Check out some of the local breweries and restaurants/bars that beautiful Portland has to offer! (Also where we had our first date if you want to be nostalgic)
This is a bit far away, but if you've never been to Maine and plan on making this weekend into a special trip, we highly recommend checking out the beautiful sights of Acadia National Park. Great for hiking, kayaking, and anything outdoors!
Beautiful beach town very close to the venue, might be a good idea for lodging as well! You can take a scenic drive along the coast and end at the the late President George Bush Sr.'s beautiful vacation home.
