Flight
Most major airlines and Southwest fly into PWM. Flights will be more expensive and most likely involve a layover. But the airport is 10 minutes from Portland / Old Port so a rental car is not needed. Cabs or Uber / Lyft are available and most hotels offer a shuttle. It is recommended to fly into PWM if possible.
Flight
All major airlines and Southwest fly into BOS. Flights will be cheaper and most likely be direct. Portland is a further 2 hour drive (without traffic) from Boston so a rental car would be needed. As this is a holiday weekend travelling by road from Boston is not advised due to the volume of traffic headed north to Maine. Unless travelling at off-peak times flying into BOS is not recommended.
Hotel
Make sure room reserved is back side of hotel. Street side rooms will deal with noise when bars let out.
