1. This isn't Busch Gardens... This is the Magic Kingdom. Gimmicks like that don't matter (and Gwazi is a perfect example of why you don't build dueling coasters when you don't intend for them to duel at all times).
2. Why would you spend money on a dueling coaster in the dark?
3. I haven't met someone that has honestly said that the layout used for our version is the worst of them all. In fact, I haven't met a person that has done any other Space Mountains after doing ours that came off saying that ours wasn't better. We have more drops (that are bigger) and we have two tracks. Ours is unique and original. Why would we lose that just to get a new layout. I would give up getting in-ride audio and a new layout for a smoothed out ride utilizing our existing layout with some new trains.
Anyways, we aren't having our version gutted. Yes, the project will be big budget, but as always, it will be more cosmetic based rather than physical. New effects, new theming (during the ride and in the entry/exit queues) and work on new trains.
