Do you have single restrooms. Ex. For someone who is blind. My daughter is taking her cousin who is male and is blind.

You can call them and talk to them. They will help you with booking the tickets and answer any other questions you might have. Here's the link to the info I found. https://www.riverbend.org/accessibility/

PNC pavilion employees do not answer these questions do user questions answered by other Google users but as somebody who's been to PNC pavilion in the past I do not think they have a single person restroom but they may have a porta potty
