Is there an auditorium where you can sit and watch media presentations about Leonard Bernstein? My husband will not be able to stand for a long time.

Yes. There are several places to sit down

Some parts yes, but not the entire exhibition. You can pre-order a wheelchair for the museum. No charge.

The benches are only for watching depictions of West Side Story: the original alongside takeoffs. Interesting, but not informative about the composer.

There are benches..it is a walk through..videos ame exhibits on going..4 floors..each a period of timeFantastic Leonard Bernstein exhibit there nowI did not see an audotorium
