As a change from running a Treasure Hunt - here is a great childrens game. Follow the links for other party games to entertain your kids:

Stations

Players are all seated in a circle. They must each choose the name of a local railway station, or a station name that is known to them. One guest will start by going to the middle of the circle and being blindfolded.

The blindfolded player then calls out the names of two of the stations. The players at these two stations must change places without going outside the circle, and without being caught by the blindfolded player.

Any player who is caught takes over in the centre, blindfolded.

The circle should not be too large for this game to be fair. If the central player has difficulty catching players, then he may be allowed to count to ten after announcing the station names. If the players have not changed by the time ten has been called, then the first named station player must take on the blindfold.
