Ditto. If you gotta go, you gotta go. Now, I will go to some extremes to avoid using a porta-potty, but even then . . . if its necessary, well, so it is. (Though we once walked a mile from the national mall so we could use the toilets in my office rather than the porta pottys there . . . ). But hey . . . stinky portas with long lines or nice, sparkling clean private toilets with no wait!
