I don't get how people stand these indoor paintball fields. Poor lighting, 100% sand floors, can't lean on the walls without getting paint on your clothes, and the game plays completely identical to paintball (ie. camo is useless). You might as well be playing paintball if you want to play at either of these locations.
That aside, you can always give them a call and ask them how their turnout is. Their number is on their site.
