How about having enough port a potties and just as important, having them at more locations and not bunched up in fewer large groups.

They should be near every food stand, as well as major places that people go like the vendor buildings, forum sheds, fly market, food court, etc.

And they should be easy to find, maybe have small signs with an arrow pointing to the nearest one.

It is great to have the few real restrooms and wish we had more of them. The ladies especially appreciate these.
