I played last year for the first time with a group of guys from work.
I have since played numerous times at marked with friends and co-workers, I even won a membership online!
Marked paintball's staff are always courteous and friendly. The refs are all avid players, and really know what they're doing which i have heard is not the same at all fields.
The staff are very clear on rules and safety.
I realize that I have no other field to compare this too quite yet, however I've always had an incredible experience at marked. always the best day out i could possibly have.
