How to fill up my class

I just opened enrollment for a live, in person class happening this autumn & I want it to fill. How do I communicate the value of the course so folks are clamoring to get in (& I end up with a wait list?) There are only 27 seats available, and only one of them is filled so far. The applications for the course have been open for less than a week.

A little background: I first offered this course in the autumn of 2017. It filled in 2017 and in 2018.

Logistics: this course is called Awaken the Mystic. I offer it to 3 separate groups of 9 women. It’s $597 for 3 days + workbooks & materials.

Awaken the Mystic is the prerequisite to a year-long study called The Mystical Year which is open to 9 women. It filled in 2018 for $1,500 a person, and then in 2019 for $2,500 a person.

I market to an email list of 1,100, and social media followings of around the same numbers. I market in-person in my area (Asheville NC) with bespoke complimentary readings and gatherings.

So, back to my original question, how do I get women stoked to sign up?

Thanks for your time & expertise!
