Well, I absolutely adore Forbidden Journey, don't get me wrong. It would have to change somewhat if what was said still holds any truth: it must change something for Deathly Hallows. What I'm saying is that the entire ride experience can have a much more fluid storyline. Music is needed in most parts of the ride, especially when you're flying with Harry. It would add to the feeling. Also, fog is needed in a much more drastic manner. Alright, let me open my list of what FJ can have done to make it a better ride experience (I should say more perfect, because right now it's perfect, but there's always room for added perfection!)
1. Music must be added to many scenes. I have a list of what songs can be played at what segments, and after some light editing, they definitely accentuate the ride experience.
2. The floo powder sections must be redone. Going through the floo network is defined as a highly dizzying experience, but obviously we can't have that. What can be done, however, is to add much more green 'fire', and have real set pieces that spin in varying levels to add the feeling of a very light dizziness, especially if there is more green 'fire'.
3. Hermione in the Forbidden Forest. She is the brightest witch of her age, yes, but there is no apparating within Hogwarts, so she couldn't have gotten there that quickly. We can, however, be guided by Firenze, Harry's centaur friend, who is naturally in the Forbidden Forast, and who can help us in getting to the Quidditch pitch.
4. The Forbidden Forest needs more fog, more lighting, and absolutely no 'lightning', hahaha.
5. The Whomping Willow needs a larger backdrop and more lighting (not lightning). I suspect that we can deduce that it doesn't notice us until we are right next to one of it's branches, hence it trying to whomp us out of there for good!
6. The last dementor scene can be greatly aided by blasting freezing air when the dementor gets close. Now, I like the face effect, but if a sort of stretching-face effect can be placed, it would work out better. Also, Harry's patronus charm is pretty small. I want a brilliant blue light to blast away multiple dementors.
7. The falling rocks scene is just unnecessary. In all that time, we could be happily flying over Hogsmeade and then arrive back at Hogwarts after that big breather. Did those rocks just suddenly decide to fall on us? Uncool.
Well, that's what I've got for helping the whole fluidity of the ride. The new set pieces (which are few: just a couple spinning fireplaces, a dozen more fog machines, a couple more 'fog-blasters', and some new lighting rigs) would only take a month to order and receive, and a month to install, and the new video sequences would just be remade by the same company that made them in that same time. Combine that with just a few new ride motions, and we're looking at another month, so we're at three; four for public testing and tweaking. In the meantime, the outer facade is being worked upon to install the new rocks and towers which were ordered to be done by a company (obviously other than Nassal...), people can still view the queue as much as they want, some beautiful new roped queue guiders are installed, and the ride reopens exhibiting new ride sequences with more magic.
Now, DC can also be worked upon, but it can be closed after the 'redone' FJ reopens in order to have no less than at least 2 rides running at once.
Guys, I over-think things. This would require more funds, and I'm more than happy with FJ how it is right now. I'm just really imaginative, haha.
