Laser tag can be a great stag party activity. Laser tag is like paintball but without the pain and getting hit by balls. This game is great because it has all the benefits of paintballing with none of the pain.
The adrenaline rushes are still there, and you can split up your stag group and face off against each other on the battlefield. Thanks to the lack of paintballs, none of you will be going home with any bruises or ruined clothes.
