For a Christmas/hoiliday party, such as a corporation, hospital, realator association, etc, I play christnas music for cocktail and dinner hour(s) then start playing dance music at the appropiate time. There are, however, some gigs where Christmas music is appropiate for the entire gig. Examples of this are a "Breakfast with Santa" which I just did last saturday at a local Moose club. Others would be holiday lunchens at a hospital, nursing home or retirement center, etc. So as most have said, most gigs would include dance music, but not all. When I do have a christmas party that includes dance music, I will still throw in some Christmas tunes throughout the night, especially slow songs, like "all I want for christmas is you" by vince vance & the valliants, etc. I hope this helps the O.P. Merry Christmas to all!
