Character mistake: When Angus is found dead, he left a word, "murder", in steam on the mirror. Daisy cleaned off the word before anybody, except Laura, could see it. Later, Daisy said that Laura was annoyed with her because she had wiped the words, plural, off the mirror. But it was only one word.
Character mistake: When Rosemary is told that the hotel the girls are staying in used to be used for movie locations until it was restored, she says that the names on the rooms are film titles and Ben, the brother of the man who runs the hotel, agrees with her. Problem is: the girls' room is called Ebenezer Scrooge, but he is a character from the book "A Christmas Carol." And Lorna Doone, another room, is a character from the self-titled book written in 1869. It was eventually made into 2 TV movies in 1990 and 2000. It's more likely the rooms are named after very much classic characters, because the hotel was used for old movies.
Answer: Regents park.
