Dracula is back - with his Pack. An official trailer for the 'Hotel Transylvania 2', the sequel to the smash 2012 monster animation comedy hit 'Hotel Transylvania' has been released by Sony Pictures.

Check out the trailer and the film's official synopsis below:

"Everything seems to be changing for the better at Hotel Transylvania... Dracula`s rigid monster-only hotel policy has finally relaxed, opening up its doors to human guests. But behind closed coffins, Drac is worried that his adorable half-human, half-vampire grandson, Dennis, isn`t showing signs of being a vampire. So while Mavis is busy visiting her human in-laws with Johnny - and in for a major cultural shock of her own - 'Vampa' Drac enlists his friends Frank, Murray, Wayne and Griffin to put Dennis through a 'monster-in-training' boot camp. But little do they know that Drac`s grumpy and very old, old, old school dad Vlad is about to pay a family visit to the hotel. And when Vlad finds out that his great-grandson is not a pure blood - and humans are now welcome at Hotel Transylvania - things are going to get batty!"
