Restrooms Available During the Kauai Hollywood Excursion?

I know, sort of a TMI question. But it's a valid concern for me, and maybe others. I see the Hollywood in Hawaii excursion is 6 hours long and includes a lunch stop. But are there restrooms available at the other stops aside from the lunch?

They aren't going to make you hold it for 6 hours. There will be at least 3 possible toliet stops.

Phew, thank you! I assumed I wouldn't have to hold it beyond the lunch stop but you know what they say about assumptions
