If this is your first time EVER visiting NYC, then yeah, it definitely would be worth it. Otherwise, I would say pass. Don't get me wrong, it's a great and long-overdue place to learn about the history of Broadway, but it's not the greatest thing in the world. I'd say go once and then be done with it.
The idea is to work and to experiment. Some things will be creatively successful, some things will succeed at the box office, and some things will only - which is the biggest only - teach you things that see the future. And they're probably as valuable as any of your successes. -Harold Prince
