If you can get to cleveland / Co durham in the North east of the UK then book a visit with friends to Battle-stations. It is the UK's only actual paintball games for children age 8 plus. We had a fantastic time when we were visiting friends in sedgefield. You need a minimum of 8 players no younger than 8 which included all the equipment and best of all, all the paintballs we could fire. Cost us £120 for all of us £15 ea and we could take our own food so we had a picnic. Got about 2 and bit hours of actual shooting at each other and about 45 mins of breaks and picnic time. Staff are very friendly and they didn't try to rip us off with extras eg Cup of tea £1.50 they only charge 50p. 10/10 kids and adults had lots of fun and got covered in paint but no bruises because of there type of low power guns (fire abt 60ft) and balls (sponge so they don't hurt).paintball cleveland - Google Maps
