If you're looking for a way to entertain the little ones tomorrow, consider taking them to the free Lowe's Build & Grow Clinic from 10-11am. They'll be building a Santa Sleigh and if they still have energy after doing so, I suggest you tell them to run around outside and see if they can fly it like a kite. If they point out it's made of wood, tell them it's magic or something. That always worked on me until I was at least 15.
As usual, space is limited, so you need to register on-line beforehand!
