I was extremely disappointed when the Disneyland version of Winnie The Pooh ended up far inferior to the Tokyo Disneyland version -- and I thought that Anaheim's decision not to use the trackless ride system was a huge mistake.
Now I learn that the Ratatouille attraction slated for Disneyland Paris will also feature the trackless ride system and that the entire ride experience will take place on a single floor of the show building.
What a minute. The drops in the Pirates of the Caribbean are essential to that experience -- imagine POTC without them. Universal made great use of a tracked motion base in the Harry Potter and the Forbidden Journey attraction by making the ride vehicles move in three dimensions.
Disney's use of trackless ride systems (with the exception of the Hollywood Tower of Terror in Orlando) appears stuck in one plane of motion. Is this a serious failure of ride design on the part of Imagineering?
