After contacting the studios I have decided to go with the Pole Fitness Studio (
http://www.polefitnessstudio.com). I have a reservation for a party of 16 for Thursday, April 18th at 2pm. The cost is $35 per person + tips for the instructor. As long as we have 15 students then we won't need Bev's coupon (though it is nice to have). The staff seems friendly (at least over the phone) and are welcoming of all ages and gender-identities. It is our private party we can do whatever we want.
The studio would allow us to invite other people to come even if they are not planning to dance. I am a little reluctant to open the class up too much - most students will not be used to having an audience. For signup it will be 1 pole = 1 girl. At the same time this is supposed to be a party so I will try and accomodate everyone. At the very least, we should bring in some drinks. If you have any questions, feel free to send me a message.
