This sounds like a cute project!
Miley will play Mavis (above), the teenage daughter of a very protective Dracula (voice by Sandler himself).
Other cast members who have signed onto the project include Andy Samberg as a "regular guy" who visits the hotel, Kevin James as Frank/Frankenstein, Fran Drescher as Eunice/Bride of Frankenstein, and Cee Lo Green As Murray the Mummy.
Good luck, Miley, and have fun!!!
