The Very Snowy Suite

There's a blizzard outside, and a family of Snowballs checks into the hotel - Mr and Mrs Snowball and their daughter, Frostina. Funella gives them the Very Snowy Suite, but when they get up there, it's not very snowy at all. The Snowballs start to feel very warm and they start to melt. But if Funella turns off the heating, all the other guests will be cold. What should she do?
