My support group matches up those who will be alone with someone willing to include them (I had a few people over for last Xmas Eve who otherwise would have been alone),

My local university has a similar program pairing up groups of people for the holidays.

I've also heard of Meet Up (no it's not a hook up site) groups that do the same, kind of like a penpal group for individuals who will likely be alone.

If you go to a church, let them know you may be alone.

There are a lot of alternatives to being alone.
