The Wampa may be right at home in the wintery weather of December, but he would tear apart your holiday party. If the treatment to Luke was any indication, these carnivorous beasts will devour your meal, or maybe even your house guests.
Don’t forget too that what we see in The Empire Strikes Back is a much tamer version of the creature than could have been. In one of the film’s most popular deleted scenes, a Wampa made its way into the Echo Base and bullied some Rebel soldiers. C-3PO was then seen removing a warning sticker from a wall to get the Imperials to meet the unfriendly beast.
In addition, Wampa pelts are extremely valuable. Trandoshans are known to have hunted them down as prize trophies, so you may end up with some precious cargo in your household.
So if you couldn’t tell from the appearance alone, I would not invite a Wampa inside.
