To me, it looks like living in the most amazing summer camp for musicians. The actors, musicians, tech staff live in a mansion on an estate, and the beach is nearby. The musicians have a little time off - the actors, none. And after playing 9 shows in 9 weeks, I would imagine that one’s pit playing abilities would be greatly improved.
One of my son’s conservatory friends said, “A summer program where I get paid, that my parents don’t have to pay for???” Yup.
