Regarding theming/immersion - I think there's gotta be a line of expectations. Obviously, we expect the best from world-class theme parks to immerse us into a fantasy world, but we also have to check our expectations. After all, reality has its limits. Seeing a showbuilding, a coaster track, etc... shouldn't ruin an experience for you, or be a deal breaker.
I know it's a discussion board - but it doesn't mean we need to debate everything. Just my 2 cents
