Hotel Transylvania 2 Overview

Dracula (Adam Sandler), worried that his adorable human/vampire grandson Dennis isn't showing signs of being a vampire, enlists his friends to put Dennis through a "monster-in-training" boot camp. But little do they know that Drac's grumpy, old school dad Vlad (Mel Brooks) is about to pay a family visit to the hotel... and when he finds out that his great-grandson is not a pure blood—and that humans are now welcome at Hotel Transylvania—things are going to get batty!
