Okay here are my two cents.
I REALLY like the idea of giving a theme to the lower lot along the lines of a port of adventure. That is great. Anupdate of JP with a more immersive queue would be ideal.
What we all have to remember though is that this is not only a working movie studio but that there are people living in the hills adjacent to the park. Noise is something that CANNOT HAPPEN. It would disturb the hillside homes, much less impede any filming. The additions would have to be enclosed or not make consistent noise. It's a very unusual constraint.
I think that for the upper lot...
-Get rid of T2 and build the Men in Black attraction there or something similar or even new. That area is a huge waste of space in a park in such dire need of elbow room.As far as the Tram tour...
-rethink the overall layout of the walkways, widen them and give serious consideration to crowd flow. The park simply feels too claustrophobic in certain areas of the upper lot and it makes for some tense situations.
I would guess that with a bit of masterplanning the paths and adding dark rides or other family type rides to the perimeter you could increase capacity and open up space dramatically. Perhaps even use the old Creature from the Black Lagoon theatre's foundation for a high capacity omnimover type of a ride.
-Fast and Furious is TERRIBLE. JUST AWFUL. needs to go NOW! Like Superstar limo did for DCA, it would improve the park with it's absence.
- Bring back the collapsing bridge if possible
- Update Jaws a little more and QUIT mentioning Murder she wrote and cabbot cove. Nobody cares except for the people too old to ride the tram anyway.
-Everything else is still pretty good and holds up well. Love Earthquake, love the older sets and the newly built ones. The War of the Worlds set is a little messy but eh, it's still impressive.
