Negative. There are restrooms in the visitors center where you check in before you start and there is a porta potty at the very beginning but then you won't see that porta potty again until the tour is over....good luck
No.
No. Pee before you start the tour!
No, you'll have to use it before you leave.
Definitely use it before you get your gear on or go on a tour. No restroom breaks!
No they tell you to go before you suit up
