Only one booked for class etiquette question

Hey yogis, I’ve been practicing yoga for a long time and also move a lot, so have been to many studios over the years. A lot had a policy that if fewer than x number of students reserved a spot, then the class would be canceled. About a month ago a new studio opened up in my area and the space and teachers are great, so amazing really that I can’t believe it just opened and how grateful I am that it did. They hold true to yogic values and the teacher/student community has been everything I could hope for. My question is that while some of the classes are full, there is one that I’ve consistently been the only student there (sometimes the studio head will go so it’s not just me). The teacher is advanced and the class is challenging with really unique sequencing/flow so I think it might be a little intimidating to some. I have a seasonal pass so don’t pay for classes individually, and I feel bad that the teacher has to come out just for me, know what I mean?? What would you do? Wait to book and only do so if others have too? Book anyway? Cancel the night before if you’re the only one? Something else I’m not thinking of?? Thanks for reading and considering :)
