We did this as a stake activity for part of our Youth Conference. It was a lot of work, but a huge success. It was a very meaningful activity. A few things we did differently are:

We started in the chapel and had a reenactment of the War in Heaven. They sang that song from My Turn on Earth where Satan and the Savior are presenting their plans. (can't remember the title). When Satan was cast out, several of the ward YW/YM leaders stood up and followed Satan representing the 1/3rd of our brothers and sisters who followed Satan's plan. We acted like we were mad and angry. You should have seen the kids faces. They were so shocked!

We were the ones running many of the booths, so we were in place when the carnivals started. We played the carnival the same way, but when death tapped you then you went to spirit prison and heard a talk on what the process is after death.

Then we went to judgment. We used all the Bishops (wearing all white) from all the wards as judges. They determined which kingdom the kids were worthy to go to based on the way they had choose to play the carnival games and the amount of earthy and spiritual tokens they had.

We had all three kingdoms in separate rooms with refreshments, and decorations that corresponded to the "glory" of each kingdom. The kids that had not made good earthy choices were really effected by it. There was such a different feeling in each room. As each youth was escorted by angels to their kingdom, they were shown what the other kingdoms were like.

We had a testimony meeting afterward. It was really a powerful experience for the kids.
