This week, our church is doing Las Posadas, which is a Hispanic Christmas tradition. I'm kind of bummed that I'm missing out on it two years in a row, because I understand Spanish enough to translate what's going on to my wife and kid.
As I understand it, las posadas is sort of like a play. Someone plays Joseph and Mary, looking for a place to stay. They go to the first inn, but they get told that it's full. They go to the second place, the third place, and so on, until they reach the last place, where the innkeeper agrees to let them stay in the stable out back. The end.
The format is pretty simple, so it can be easily adapted depending on how many people there are. At our church, they have designated adults at certain places, to be the innkeepers. Everyone else is part of the group, looking for a place to stay. There is some singing and pinatas. Overall, a nice little event for the kiddos.
