A winter festival is not a Christmas party. That distinction matters. A Christmas party is small-scale and tightly focused on Christmas. A winter festival is something different: larger in scale and open to a broader audience.
A winter festival is about the atmosphere of winter without the obligations of Christmas: no Christmas trees doing the heavy lifting, but ice, light, warmth, spectacle and experience.
A winter festival works for groups from around 200 people upwards. Smaller than that and you lose the festival atmosphere. Bigger than 2,000 is fine too. Winter festivals scale well.
