No, your ideas are VERY reasonable. The trouble is, there's a difference between the theme of TL and being "Disney".
The story of TTA (perceived from the old narration and thematic elements) is that you would be taking a "Transit" system around Tomorrowland on the "Blue Line". One could perceive that there are other "lines" (similar to subway lines), like the Red Line (a line to other interplanetary destinations in the galaxy) or Green Line ( to the "hover-burbs"), that interconnect to other parts of Tomorrowland besides this downtown district. We're supposed to believe that real citizens of Tomorrowland, be them alien or humanoid, monster or otherwise takes this system to get to wherever they need to get to in the bustling city of Tomorrow. This theme is reinforced by the old "Please keep your hands, legs, and tentacles" spiel. Soon, we're whisked off on a tour of Downtown that goes through not only the rides, but also fictitious places such as the Interplanetary Hair Salon and things like that, still visible on the tour. A booming robot voice announces each new destination, as if you could actually get off at a diorama window and get your hair cut by robots or something. There are also traffic and weather reports (of course a necessity when you're a busy interplanetary traveler!) and other interruptions. The tour ends, but you never really get a good description of Tomorrowland that exists, just a visual representation. You get a better view of the fictitious Tomorrowland that exists in utopian fantasy.
The new ride begins with the reference to the "Blue Line", but abandons the idea of travel there. You enter the ride with a new purpose, as a tourist visiting Tomorrowland for the first time, as many riders actually are. In this incarnation, you get more tangible and usable information through a more generic voice, but the delivery of the lines feel like a vacation video. It provides great insight on what's inside of each show building and why Space Mountain's closed. You also realize what that big spinning building is; turns out it's an animatronic show! You come off the ride feeling enlightened as a first-time visitor, but the rich storytelling of the old ride is missed.
Why can't there be a happy medium?
