One of the challenges of planning a HOA New Year's Eve party, though, is coming up with ideas. From party themes and favors to activities and costumes, here are some of the best ideas for New Year's Eve events: livestream the ball drop, stick to a simple dance party, countdown with a movie marathon, bring Vegas to your community, get started with a workout party, get fancy with a masquerade ball, get competitive with games, have a bubble-themed night, stay comfortable with a pajama party, have some fun in the sun with an outdoor party, and have a virtual party.
