I actually asked a TM this a couple of months ago why they have simple names for rides and from what they told me, it usually has to do with the fact that there are a bunch of guests that don't realize the ride is there or they think for some reason they have to pay extra for it and complain about it. When I asked them what they meant by that, another guest came right up and asked where the actual Simpsons ride was because they only rode the Krustyland ride and have been looking for "hours" for Simpsons.... So yeah.... I'm gonna have to go with that reasoning
