Everest, Test Track, American Adventure, Illuminations, Paint the Night, Indiana Jones Adventure, Star Tours, California Screamin, Golden Zephyr, Tower of Terror Paris, and pretty much anything from Arrow in the 1950's would like a word with you.
Still though, Disney's arrogance with the LPS system is 50/50 on them and their tech partners. I still have yet to understand why basic emitters and rader weren't used. The supplier doesn't exactly have a good track record with positioning systems- just look at Sea World's antarctica. Weatherproof projectors that were neither ventilated nor weatherproof aren't really Disney's fault but they probably could have done more internal testing rather than taking suppliers word for it. The poor fidelity on the screens has been addressed to most people's satisfaction I guess. The flow of the show is good, though the cuts could be better done.
