This is disinformation.

Rowling may be an awful person but she bought the yacht in 2023. He was long dead. The yacht may have been a ferry to his island but she wasn’t the owner at the time, and it wasn’t for hire or a shell company.

There’s no evidence that she approved or was involved in the invite to the show either. Rich people have assistants for this sort of thing; they don’t want to be bothered (on their estate) by some other rich person asking for tickets to a show they had someone ghostwrite.

On another note, it's criminal to refer to 😱 as a Home Alone face.
