Atlanta has tried a lot of things at its two dances (!). One of them uses
sliding scale, and it strikes me as a good way to go for many groups.
Sliding scale avoids the need to define categories like "student" or
"minor" and to just say, use your heart. It has not been abused as far as I
can tell. The other dance uses $10/event--a nice, simple round number that
I hope covers the costs.
The older and bigger dance tried an annual subscription a few years ago,
while I was on the steering committee, and it was not continued after the
initial one-year experiment. I do not have the info on hand to say exactly
what did and didn't work, though I know there are polls and financial
analysis that are floating around. I better not reconstruct it just from
memory.
It isn't happening any more, but another group named Reframed offered the
best subscription approach I've ever seen. The subscription would grant
access to every event the organizer put together, which included a weekly
contra dance and also thirteen other dances at one extreme. An individual
event would either be free or would cost about $10, and I think the monthly
subscription was around $40, but I can't remember for sure. The simplicity
of it was wonderful for everyone involved, and it seems like it gave the
organizer the opportunity to do a lot of experiments in both the dance
line-up and in the role definition of quasi-volunteers within the group.
Reframed definitely had--has, I suppose--that club-like feel that I see
mentioned in other posts on this thread. People hang out on the Discord
with each other, and the subscribers would sometimes go to an event almost
every day of the week. So it was quite the social hub for many of the
members. Also, it struck me that these highest attendees were not at all
moochers but were more like volunteers doing a lot of free work. When they
would go to an additional dance or two a week, they don't really cost
anything since they wouldn't have gone if the subscription didn't exist.
Meanwhile, they do a lot to help out, including helping out the new
dancers. That factor is important to consider for a subscription and makes
it not as simple as ticket revenue minus operating costs.
