It seems the franchise studios seem to charge up to your first born to become a dancer. As far as comps go, I know someone who used to dance in them (he was the pro) and it doesn't matter how good you are in most of them (just like the shows) it's all popularity. Obviously the student who pays the most, is the most popular.
As far as just dancing socially, you know just to have fun, I go to a studio, non - franchise format, that has almos any package to fit what you need. From begginner groups to private lessons. Private lessons are also a flat fee, sold in 5 or 10 weeks which include the groups. Even the groups cover all levels. In response to "Guests" comment about once you reach a certain level, basically you have no need for groups, the group levels at this studio include beginner, intermediate, advanced, and a technique class.
Sorry to keep going on and on about this, but after reading almost every post on here and I see prices that cover thousands of dollars, for a fraction of the price, you can some much more than you are getting, with experienced instructors, not someone off the streets that's one week ahead of you.
