The state of Maine has a detailed plan for any out-of-state visitors planning to stay in Maine. There are two options for guests: self-quarantine for 14 days in Maine, or have evidence of a negative COVID-19 test (PCR or Antigen test) using a sample taken no more than 72 hours prior to arriving in Maine. You may also quarantine in Maine while awaiting the results of your COVID test. Then, you must complete and sign a Certificate of Compliance. They have a great FAQ webpage that explains everything in detail, found here: https://www.maine.gov/covid19/restartingmaine/keepmainehealthy/faqs
Unfortunately, COVID-19 has meant limiting our guest list to immediate family members, and family members already living in the New England area. Each guest will need to take a COVID test close to the wedding date in order to comply with Maine's COVID-19 policy for out-of-staters.
The ceremony and reception will be both indoor and outdoor, so masks should be worn indoors.
