I don't understand why a Children's hospital would want and accept a pinball machine from a charity. High maintenance, loud, I would expect it would need to be wiped down constantly due to germs....in a children's hospital. Is a nurse expected to take off the glass to free a stuck ball? Stuck balls probably last for weeks and render this huge game inoperable. Some kids will need to stand on a stool. Nice.
An Arcade 1Up pinball machine is what should be placed there, if anything pinball related. A few Arcade 1Ups are all that's needed for the kids. Perfectly sized , quiet and enjoyable.
