Yeah, I think what I described is what I think a lot of MT kids do in HS who are the type who are thinking to go to a BFA degree program (or even a BA one). In my kid’s case, there was a lot of car travel time. We also did not have a PA high school. The only related things during the school day were jazz band, chorus, and private guitar lesson. But piano lessons, shows (except school musical), dance classes and rehearsals, voice lesson, monologue lessons, & some theater productions were all outside of school and not nearby. School musical, musical revue production D created, and a cappella were at school, but after school hours. Schedule conflicts did arise! By the way, my daughter who did not go into MT in college had just as a full of an activity schedule after school, evenings, and weekends, as my MT daughter. I don’t think they are unique in this way.
PS, I will add that if your kid doesn’t go to a performing arts high school, or goes to a high school that doesn’t have a drama program/classes (but does put on 2 shows per year), you have to piece together the training and production experiences outside of school and outside of the school day. And if you live in a rural area, you have to travel to put together this stuff.
