The have regular bathrooms
They have a fairly large selection of food and drinks. I don't know about bringing in your own. The staff is very helpful, call them at 208-322-5000 and they can answer any questions.
They do have a concession stand. Not 100% sure about bringing your water inside. I'd think it would be available in the concession stand. Hope this helps
You can bring in your own drinks. Doesn't have to be water.
Also do they have normal bathrooms or port a potties? My son just started potty training 2 weeks ago and just trying to be as prepared as possible lol
