I just had one 2 months ago. Unfortunatly, I was in the noisy area, so do bring some headphones & great ear plugs. I would have left shortly had I not had them. Whining complainers I have no patients for. Had a DVD to kill time. Like it's been said, anything to keep from being bored to death.
Comfy clothes. Gowns are a joke, so pack his every day wear. As stated prior, eye patches come in handy.
Aside from the crappy food, noise & that cord that kept being twisted it was not a big deal.
