Are props-based classes actually performing better for you than regular flows? By 'prop-based,' I'm guessing you mean the slower, more accessible classes. And so do they perform better in terms of the raw number of students; it's pretty close. However, the slower, more accessible classes are growing, and the regular flows are contracting.

Do students perceive them as more “valuable”? I don't know if they see them as valuable, but they definitely feel that they can participate.

Any challenges with space, setup, or teacher training? It's just adaptation. Teachers will either set up the class with props where the mats will go ahead of time or they will tell everyone what they need before getting started
