The game itself was mostly exciting, however, there is not a whole of of fan interaction especially for the kids. Setup some booths for the kids so they can enjoy the entire experience, not just the game. Setup a hockey shooting exhibit for example. Have some sticks shoot some pucks at a target, etc.
Take some actual size images of two best players on the team put them up on the wall, with a measuring tape, kids stand next to the players and compare. Small stuff like this goes a long way!
