From what we saw in October nobody got turned away - even though some of them had broken some of the rules (e.g. no full face masks - we saw a few of them)
They do say that you are not allowed to stop and pose for photos with park guests but we were regularly stopped by people and asked for a picture with them. Even when we were sat on a bench they came and sat next to us for pics, even taken a shot without even asking a couple of times.
To us it just meant that we had done a good job of our costumes and made the night a bigger success for us
