I've advocated for a memorabilia museum for a while now, it's something cheap that many people would have some interest in (and even if you're not interested you'd still probably have a look) and gives the park a bit of credibility. It's strange to me that the park is 'Movie World' with the studios right next door but there are no references to the studios in the park.
An attraction that literally everyone can do is also badly needed at MW so massive thumbs up from me. A studio tour in the long term would be cool now that the studios actually have an interesting history but for now pleased with that move.
As for SW, what can you say that hasn't already been said? I guess one potentially new observation is Ray Reef, Paw Patrol and the new undercover Plaza for events are all attractions that you would add to SW if you were focused on the resort first and the park second. Ray Reef is the sort of thing that belongs at a resort really, Paw Patrol (license aside) is not something a decent theme park would highlight as if it's a motivator, and the Plaza, despite being a huge improvement is an events space.
Don't get me wrong either, the resort is fantastic right now and the leadership there has done a great job, but SW really needs someone who cares about the park as a theme park, not as the resort's really elaborate Kids Club.
Also do they still own WnW GC? Can someone check that and let them know if they do because it seems to be looking pretty forgotten about.
