Just a comment on my son’s experience with walk-ins at Chicago Unifieds (Acting, not MT). He was walking the halls on the first morning just looking around at options before his scheduled auditions - he was invited to do a walk-in by a random school that was not on his radar (Univ of Utah). Apparently they had open slots. He went for it, had a good audition, got some nice feedback. More importantly, it got his juices flowing, completely settled his nerves and put him in a great frame of mind for the rest of the day. Call it a no-pressure practice round. It wasn’t his plan, but its not a bad idea in retrospect.
