Hello Julia and thank you for bringing such a great question to the Disney Parks Moms Panel.
I feel very blessed to have attended a live performance of
Disney's Pixar in Concert whilst it was on tour here in the United Kingdom, it was utterly amazing and I wouldn't have missed it for the world!
The
Music of Pixar Live! - Coming Soon! is set to debut on May 26th 2017 in the
Theatre of the Stars at
Disney's Hollywood Studios and currently is not offering Guests a
FastPass+ option.
Guests are set to be entertained by this
Disneytastic concert
3 times nightly which means there should be plenty of opportunity to enjoy great seats without the need for
FastPass+, however as always everything is subject to change at Disney, so this may or may not change in the future.
In the meantime you might be interested to check out this
Disney Parks Blog - The Music of Pixar Live! will debut at Disney's Hollywood Studios this Summer article.
Have a great Disney day!
