If you want a unique ride system... what's left?
Two systems that WDW does not have are a ferris wheel and a kuka arm ride.
For repetitive systems:
- WDW has six omnimovers (Buzz, HM, Mermaid, SSE, Nemo, Midway).
- Will soon have 9 coasters (Cosmic, TRON, Goofy, Space, 7D, BTM, SDD, EE, RnRC), and if PW stuck around, it would have been 10 coasters.
- Has 7 slow moving boat rides (OK, two have a minor dip -- IaSW, Gran Fiesta, LwtL, NRJ, PotC, FEA, JC).
- Has 7 spinners: Teacups, Carousel, Dumbo, Astro, Carpets, Alien SS, Triceratops
- As far as SCREENZ! go, only has 4 simulators: Soarin', ST, MF:SR, FoP.
- And just 3 LPS: RotR, MMRR, Rat.
So... I wouldn't say LPSs are being overused, even if they add one more in a park that has none.
I would also note that it seems WDW can never get enough "family coasters," as they are constantly the most popular rides.
