If you ever find yourself in Alameda, California, definitely check out the Pacific Pinball Museum. It's a non-profit with a ton of playable machines dedicated to restoration and preservation.
There were of course people not adhering to the 2 game limit and hogging the popular ones like Indiana jones, Adam’s family, etc. overall though a good experience and would recommend to anyone.
They also own a whole warehouse out at Alameda Point filled with machines. I know they have provided some form of access to the public in the past, but I'm not sure what that looks like today.
