Suggestions for the Christmas party, what should I do?

My husband and I have several people staying in our house over the Christmas, and we are to have a Christmas party. I asked my guests if they had any suggestions for Christmas, because the old-fashioned Christmas and the up-to-date Christmas were both so played out and I wanted to have something really original this year. Blanche Boveal came up with the suggestion: she said that she stayed with the Mathesons last month and they had such a good idea. Every one in the house-party had to be a character and behave consistently all the time, and at the end of the visit one had to guess what every one’s character was. The one who was voted to have acted his or her character best got a prize. She said that she, for example, was St. Francis of isi, and Colonel Pentley was the Jolly Miller on the banks of Dee, and so on. I thought it was a good idea, and decided to have it at home. But my husband is not so enthusiastic. He thinks it's not wise. He said that it might do very well at the Mathesons, where they had rather a staid, elderly house-party, but here it would be a different matter. There was the Durmot flapper, for instance, who simply stopped at nothing, and Van Tahn, and Cyril Skatterly had madness on one side of his family and a Hungarian grandmother on the other. He said that we didn't know what Skatterly’s Hungarian imagination mightn’t do. In short, he acts as an alarmist. So, should I have this game at Christmas or not? What should I do?
