Personally I agree with those who want expansion, but not DA. I mean I just don't understand why so many people are hoping for Diagon Alley. More shops and another roller coaster?? And as I and others have stated DA and Hogsmeade would look like exact counterparts! Imagine walking into the Wizarding World and seeing: long, cobbled street lined with shops and restaurants, off in the distance, towering iconic building housing main attraction, passing this and seeing yet
another long, cobbled street lined with shops and restaurants, with a towering iconic building off in the distance, housing another main attraction! Just sounds silly to me. It would be like building another street behind Tower of Terror called Twilight Blvd with the Tower of Fear at the end.
As for Diagon Alley itself, there is a reason the creators chose Hogsmeade/Hogwarts instead for the original land. There just isn't that much to do in Diagon Alley - it's like a big shopping mall. A shopping mall and a bank (even magical) can only be so exciting, IMO.
As for the Gringotts coaster, :bored:
Do we really need
another coaster when we already have Hippogriff and DC? In any expansion I would hope for a different type of attraction to add a little variety (such as a slow dark ride ala Haunted Mansion, special effects show, or just anything else besides another roller coaster). And this is without even considering what the story would be (taking a tour and then being attacked by a dragon?? Sounds familiar...)
This is not to say that there
won't be a Diagon Alley expansion, just that I would much prefer something else.
The only way DA would work, IMO, would be if the WW took over the entire LC, the Greek section becoming Diagon Alley with the Arabian section getting its own separate HP theme so that DA was a good distance away from Hogsmeade. The problem with this is that the park starts to look like the Wizarding Islands of Adventure, considering it would have probably 3 times as many attractions and shops as the other lands. Which I guess they could make it work somehow (Harry and his friends have accidentally opened portals into 4 other dimensions??
)
