I went to the Silverball Museum in Delray Beach, FL last Friday. They are enforcing masks and have hand sanitizer and wipes - everywhere. They also have a bunch of Skee-Ball machines and request that patrons put on gloves before playing them (provided - no gloves required for pinball, but you can certainly wear them if you would like to).
I went earlier in the day when they opened and had the place pretty much to myself for a couple of hours. I'm not sure if they are limiting the number of people allowed inside, but it's a pretty big place. There were probably 10 others in there when I left.
I felt perfectly comfortable going there and used hand sanitizer and common sense. I would not have gone in if it was packed full of people.
