Well, the room with the leeches that scuttle across the seats this year will be based on the Merlin boardroom, with the leeches replaced by management, scurrying around to bleed every penny out of their guests.
While the "doctor" will rip the very heart out of the resort and show it to everyone.
The end scene will be the drop shed, where everyone will be crammed into one of the new enchanted sheds, and shown a promotional video about stargazing, before the floor opens and drops all their expectations into a pit, never to be seen again.
