Alton are starting to get alot more limited for space, However i dont see anything being removed coaster wise, Im not sure if the park own the land i have highlighted but i have got a few spaces that the park could expand into.
I think with the paramount park they need a new area, As the paramount park is aimed at family's i can see it having some sort of record and opening the same year as the new paramount park. I think it will have some basic family rides with amazing theming. I think they should go for a bit more of a teenage target market that kids still watch, I think the simpsons would do the job. I think this would be best in area 3 behind oblivion, using the submission area as a entrance and having the main entrance in cloud coo coo land. Then repaint up sonic and move that in the area, along with a disco-coaster (doughnut disc yellow track with a homer in the back) I also think the park lacks a 4D cinema, Ice age has good effects but id expect a funfair to have better (bench seats with fans under them and foam machines) So a 4D cinema building all themed as different simpsons buildings. I also think alton need a new thrilling flat ride, and the area should be thrills and family, so id say a s&s swing type or intamin/fabbri/huss/KMG gyro swing would fit well (could have many themes) And some fun family rides like a outdoor waltzer/twister and a dodgems (In follow with thorpe park) and a vekoma family suspended coaster like what fun spot now have. I think the area will also have a zamperla air race 8:4 model with simpson theme, a skate boarding theme would be cool! I think alton will go with 1 main manufacturer for the area use alot of zamperla kids/family rides in the area so they can market it as a family area but have the big rides in still to get teenager market groups in. I think the park would continue to do excellent and make paramount have some good competition, however merlin needs to take a huge step with theming because past paramount parks (Kings dominion) Have volcano the blast coaster with good effects and a huge volcano. Kings island had the crypt and the theme on that was beyond disney and univercal. So i think they will add a dark ride in dark forest probably make a path down after 13's entrance.
I know Alton will have something up there sleeve and will have a amazing next few years and stay the best UK Theme park, So im not worried, But i dont see a 4D B&M, it wouldn't fit the park at all, If they go to B&M it will be a wing coaster and will probably just be a good ride like the swarm. However i dont think they will get a wing coaster because there next ride needs to be a massive gimmick to cram newspapers and radios to stop the paramount park getting 100% publicity and attention.
