Thanks Morgan, you make some really nice suggestions in your post too! My suggestions are really just the base minimum I'd like them to do, so I definitely agree with some of your ideas!
Very much agree with you about CCL. Reopening on the theatre, as well as all the current SBNO rides is a must, but I'm pretty sure that will be happening should that areas ben rethemed in the near future. Sadly, I just don't think I can see them moving Frog Hopper again to open up the entrance to the theatre, let alone put on an actual show in there!
Spinball is another interesting one. That really would be a loss to the park if it were to be removed, especially with how operations are at the moment, as well as it being one of the park's best family coasters. I'm kinda hoping that it doesn't go. I mean, there are other things on the LTDP which never actually happened, so hopefully Spinball is another one of those things. Having said that, the council are very keen for it to go, so who knows?! I'd be very very disappointed if Spinball did go, and then the 2019 addition was just another expansion of CBeebies Land. A dimply ride needs to be replaced with a family ride in my opinion, and CBeebies doesn't ally fit into that category. And when there are areas lie CCL which need the attention much more urgently, I really hope that that is the area that will be refreshed for 2019, without Spinball being removed.
Forbidden Valley, whilst I do see the importance of a thrill ride to replace Ripsaw and reopening Sub Terra, and that must come first above any other additional rides, but I think it's the one area of the park were it doesn't quite cater for all ages, and a new family flat ride near Galactica would definitely fill this gap.
For X-Sector, I really really like the idea of a Tourbillon – I think that could work very well for the area, and would fit the theme nicely as well! I'd still worry about the lack of family options there, but at least it's not as isolated as FV is. Again, the Dark Forest, ideally more than one new thrill flat, as there is I'm sure quite a few spaces where they can put these in the Dark Forest.
