The subject matter is not family fare which many tourists look for.
You mean family fare like Phantom of the Opera, Chicago, Les Miserables, Avenue Q, Book of Mormon and Spring Awakening? Or family fare like Tarzan, Big, Seussical, Little Mermaid, A Year With Frog and Road and the last two revivals of Annie?
