HOLIDAY OPTION
There is an option for alone folks on the Holiday. Some people, to no fault of their own, end up without family on the holidays.
Post a Craigslist ad or meetup.com early on to other people who are familyless on the holiday. Agree to meet initially for coffee a week before. Be selective. Get four similar people and play board games on Christmas eve.
Be creative with social skills. Then always tailor the group for cohesion. And just have fun. Meet new people.
I started a conservative Thanksgiving dinner in NYC last year. Only 5 people, because a bunch got invitations elsewhere at the last minute, but this year there were 11 and they had a great time. New friendships, the lot.
Next year will be even better.
