In the present day, a few months after the events of the previous film, Dracula is running his hotel business smoothly with his daughter Mavis (Selena Gomez) and son-in-law Johnny (Andy Samberg). However, Drac is depressed by the fact that, since his wife’s death, he’s lonely, despite attempts to meet someone new. Misinterpreting this, Mavis announces that they will be going on a cruise so he can get a vacation from giving vacations and spend more time with his family. The next day, Dracula, Mavis, Johnny and the rest of their family board a cruise ship called the Legacy. Dracula sees the ship’s human captain, Ericka (Kathryn Hahn) and falls in love with her, something he thought was impossible.
Meanwhile, the hotel chef Quasimodo (Jon Lovitz) with the help of his pet rat Esmeralda learns that Johnny is a human and kidnaps him in order to cook him. Dracula intervenes and magically freezes Quasimodo to keep him from telling anyone that Johnny is human. Dracula leads Johnny to his quarters and shows him a painting of Martha, allowing Johnny to realize why Dracula built the hotel and became overprotective of Mavis. Johnny then agrees to leave for good, but Dracula convinces him to stay for the time-being to avoid ruining Mavis’s birthday.
The party is a great success the next night, and Mavis looks forward to opening a gift from Martha. However, when Johnny and Mavis share their first kiss, Dracula overreacts, and, in his outburst, inadvertently confesses to deceiving Mavis with the town. A still-frozen Quasimodo bursts in and Mr. Fly (Chris Parnell) reveals from his frozen speech that Johnny is a human disguised by Dracula. The guests are outraged by the deceit at play, but Mavis is undeterred and wants to be with Johnny. Johnny feigns disinterest in Mavis and rejects her out of respect for her father and leaves the hotel.
