The (mis)adventures of monsters residing in Hotel Transylvania, a plaza hotel where monsters can relax and get away from humans due to fear of persecution.
Welcome to Hotel Transylvania, Dracula’s lavish five-stake resort, where monsters and their families can live it up and no humans are allowed. One special weekend, Dracula has invited all his best friends – Frankenstein and his wife, the Mummy, the Invisible Man, the Werewolf family, and more – to celebrate his beloved daughter Mavis’s 118th birthday. For Dracula catering to all of these legendary monsters is no problem but the party really starts when one ordinary guy stumbles into the hotel and changes everything!
Seven years after the events of Hotel Transylvania,<ref name=InquirerFacts /> Mavis and her new fiancé Johnny are finally married, with the approval of her father Dracula, and the world becomes aware of (and unfazed by) the existence of monsters. A year later, Mavis reveals to Dracula that she is pregnancy and gives birth to a baby boy named Dennis, who later befriends Wayne the Werewolf's daughter Winnie. Nearing his fifth birthday, Dennis has yet to grow his fangs and Dracula worries that his grandson might not gain vampire powers. Noticing the dangers of Transylvania, Mavis starts to consider raising Dennis in California where Johnny grew up, much to Dracula's disapproval.
In 1897, Dracula and his friends travel in disguise on a train to Budapest. Professor Abraham Van Helsing, Dracula's arch-enemy, boards the train and unveils the monsters; the monsters escape by climbing through the roof, and Dracula pushes his friends from the train for their safety. Van Helsing is obsessed with destroying Dracula but is constantly outsmarted by him.
