Why don't you try and see it from a 'kids' eyes?
Anyone under 13 can't play paintball (legally) - so why not give them the next best thing.
Or would you rather they had 10-y-olds with paintball guns - shooting anything that moved?
My 10-y-old recently went to a Laser Quest place - and described it as 'awesome' - and he does play paintball (all be it against me).
He won every game he played in - simply by using his paintball 'skillz'.
And as much as you wouldn't like kids running around your ankles - they wouldn't want you whizzing around their heads with loaded projectile launchers!
Lazer tag has it's place, along with Airsoft, why not simply leave it alone on concentrate on your game (when was the last time you heard skateboarders whinging about BMX'ers and vice-versa?).
Work with them - not against them!
I dont think it would feel the same as paintball, so I'll never try it
