So, frankly, I'm looking forward to seeing how things work out there. I think it'd detract from the experience, personally, at least the immersiveness, but I guess in less than a month we'll know for sure.
As far as Harry Potter land, I think it will be a visual feast, even for those who don't like Harry Potter. The scenery will be the best part of the area. The rides will be good too, but if I'm not mistaken, some of them are existing rides that have been outfitted with Harry Potter themes. I don't have huge expectations for the individual rides, but I do expect the area as a whole to have a lot of details.
As for the ride, it probably will be short, slow loading, break down a ton and probably will be amazing. I don't think they can afford it to be lame.
I do find it funny that the best animatronic the park has is the sorting hat!
And it has been said millions of times but it is true that the shops in hogsmeade are tiny.
But to stay on topic... yeah the forbidden journey will blow spidey away!
As to HPL, there is one new attraction with re-theme of the rest of the area. Most people aren't acknowledging that. The new ride sounds cool but, I'm saving my excitement until I read reviews and see u-tube clips.
Just my 2 cents.
BTW, Emma Watson is getting really cute.
