I agree. I used Low light mode in a dark setting at a wedding with LED lighting and it was all blotchy like your footage in the mansion. I had it on Reg D-Log with the 50 - 3200 iso and it looked much better in post, but unfortunately I changed it to low light thinking it would be better. nope. However, I have used the lowlight in other situations and it's looked great.
I am more worried about the connection between the battery base and the piece you screw the tripod into. It seems weak, I am afraid I will lose the camera from it coming apart.
Were you able to take the mini tripod with you? I will be there solo so I need tripod to take pictures of myself and I know Disney policy is not getting their with tripods
Also, just in case, put the mini Tripod on the camera and close it so it just looks like part of the camera and hold it in your hand when you walk through and they probably won’t even look at it
