I had a quick look on the websites for laser tag, same as laser quest and it says....
Is laser tag safe?
Laser tag is an indoor physical activity. While it is supervised at all times, and we make every effort to ensure strict adherence to all of our rules, and prohibit running, we cannot assume any responsibility for any injuries that may occur. Our lasers are Class I laser products, and have not been directly linked with adverse health affects. We also employ the use of commercial fog, which is composed of food-grade mineral oil. If you are asthmatic, epileptic, have a heart condition, are currently pregnant, or if you suffer from any other health condition, you are personally responsible for deciding whether or not playing a moderately physical activity will be detrimental to your condition. We cannot under any circumstance give medical advice as to whether or not laser tag will pose a risk given your individual health record.
My biggest concern would be being pushed around or falling over!!!
Have fun if you do go!!
