Info on Universal Studios HP Venture
Those that were in the planning of the Wizarding World at Universal Studios, had the following to say:
It start with Hogsmeade station into the park. To its left is Zonko's, Honeydukes, and the Three Broomsticks (serve pumpkin juice and butterbeer). across the Three Broomsticks is the Owlery (a 'calm environement' with owls atop), next to it is the owl post office. Ollivander's wand shop is to the post office's right. Inside of the wand shop will be thousands of dusty-old wand boxes. Dervish and Banges will have wizarding memorabilia like sneakoscopes and much more. there will be The Dragon Challenge & Flight of the Hippogriff
(plus two roller coasters). Finally is the entrance to Hogwarts and the castle coming to life.
Tom Felton announced that to his knowledge, the opening date of this part of the park will be in Spring of 2010.
