I can't wait for this expansion and I can totally see why Universal are going for it. Of course it's for the money but that is business full stop.
The beauty of the HP franchise is the large universe that has been created with the books and the films. Beyond the castle itself there is ample oppurtunity for rides, gift shops, shows and everything else. What I loved about the IoA part is that it also utilised some characters that were never actually seen in the movies and one that wasn't even mentioned.
Universal are definitely aware of just how much they can do with it and just how much the fans will enjoy it and hopefully boost the gate numbers for both parks.
At first I didn't agree with the two different HP sections being included in different parks but the more I think about the more it makes perfect sense. The wizarding world fits really well into the IoAdventure 'theme' whereas the hidden London section would fit great in the studios. I didn't particularly like the fact that they want to ensure people get a 2 park ticket BUT in a business sense it is a clever way to ensure people visit both parks.
I wonder whether they are going to give this area its own name or whether it will also fit under the Wizarding World banner, since they are in different parks it may be a little confusing perhaps.
I remember seeing HP7ii and commenting on how the Gringotts section was blatantly designed with the theme park franchise developments in mind. I am sure others on here said it too. I always knew the Gringotts Vaults were 'coaster-like' from the books but in the films it was like they literally designed the whole thing around one.
Still, what I really wish is that Warners would take the whole world of HP and turn it into a standalone park in the UK (where the weather is actually like what it is supposed to be
). It would be a massive task but it would also have pretty good tourism and economy benefits too. Oh well, I can dream...
