If I remember correctly, there was no plastic shields at the tables. Certainly at Hollywood when I was playing roulette, there were no shields. Instead of high fives, there was a lot of fist bumping going on! The machines at Hollywood have dividers in between most if not all slot machines but they were more permanent than plastic. I looked at those as more like "privacy" screens. There were signs on the machine to show the machine had just been cleaned. They were very good about cleaning the machines once you got up and moved on.

At Casino Royale I saw more of the plastic shields around the slots --didn't notice much at the tables. At the Princess, I don't think I saw a plastic shield at all. That seemed to be the least Covid conscious casino that we visited.
