It is a minimum of $6 for the arcade. The $6 is credited towards the booths, which still take bills to add to your $6 credit.
It's one person per booth but often guys leave their doors unlocked. Don't be obvious about stepping inside with someone. Don't yank on doors that are locked. You'll get asked to leave if you do. Be courteous. Some guys truly are back there to run one out on their own. Leave them alone.
THEATERS
It's $9 for entrance to both the all-male and straight theatres. Big rooms with open seating. Both theatres have chairs. It can go back and forth between the straight and all-male theatres. Couples often are in the theatre. Plays straight, bi and trans movies.
