Escape New Haven does private bookings where you can rent out the whole venue. You cant fit a huge group all in one room, but up to around 30 people can play all the rooms simultaneously. Their website should have all the pricing info
Depends on size of group, pretty sure they don't have rooms for over 8 people at once. You can book any number of rooms you'd need online, but you would have separate groups depending on your total size
