We did this with my son and he really enjoyed it. Most of them invite the kids up front to sit and interact with them while they tell the story of their country. It did bring some confused questions from my son about the "real" Santa, but it was fun. After they're done they stay for a few minutes for pictures, which is usually the only sort of line that forms. We have a neat collage at home of him posing with each of the Santa's that we put out at Christmas. Check the schedules for them - we were able to go from country to country and see several in a night. I think they come out once an hour, but the countries are staggered about 30 minutes apart (I think)
