Do Not Disturb (2016)

Anna and John book into the Stratford-on-Avon hotel where they spent their honeymoon 10 years earlier--separately, following Anna's extra-marital fling but they had paid for the room anyway. They decide to give their marriage another go but then Anna sees young Luke, hung-over best man from the previous night's stag party, who mistakes her for a prostitute; she rings receptionist Sheila to get rid of him. Meanwhile, two real escorts arrive and assume that porter Neil is their client, to Sheila's annoyance. Confusion arises when a blindfold Anna has sex with Luke by mistake and Neil ejects John, believing him to be Luke. By the time Anna's mother turns up, there is much explaining to do.
