That's what you do after you drop a load on R&D for a ride system.
Haunted Mansion, Little Mermaid, Nemo, SSE, Buzz, Pan, Horizons, World of Motion.
IASW, PotC, Rio de Tempo, Maelstrom, NRJ.
Star Tours, Body Wars, Iron Man.
Spider-man, Transformers.
Kong, FF:SC.
The trick is to change it up enough that it doesn't feel like the same ride. PotC and IASW do that the best. Spider-man and Transformers the worst (reasons).
