Can I file a lawsuit for being denied access to a public restroom in nj?

I purchased a membership to a theme park online before attending. Upon arrival my children had to use the restroom. I asked the girl whom was helping me if my oldest daughter could take my youngest 2 children ages 2 and 3 to a restroom, she walked us to a mr. Bob with an out of order sign on it than said sorry, than we walked back to get our passes, still not having used a restroom. We wait a little while than asked another person she said there was only access to the one mr bob. They were having difficulty with processing my membership so I was sent to stand in yet another line, now with 4 children whom had to use the restroom. My tickets were already paid I had my reciept the barcodes on the pages I printed wouldn't scan. I asked a 3rd employee if my daughter could please take my 2 year old to the restroom and was again denied even after showing my paid admission receipt. This ended in my 2 year old crying and having an accident in line.
