Such a cute idea for a Christmas/Holiday party with kids present. Always kids present at Military functions. Hot chocolate bar- must do this! (link to crock pot hot chocolate recipe that is supposed to be good!
"Elf on the Shelf" alternative - the "Wandering Wisemen." Move the Wisemen around the house as they search for Jesus. The kids have fun finding them all over the house. They Wisemen can face obstacles, maybe stop for food and drinks etc until Epiphany
