I couldn't agree more. To me what today's management misses and that the old guard understood was that ALL of WDW was the stage. Any place a guest could go and how they got there was part of the show. Of course even the old management wasn't perfect, but they sure tried a heck of a lot harder than what we see today.
Monorails, watercraft like Southern Seas, etc., were great for the exact reason that you already stated: They weren't part of your everyday life and didn't just take you to a physical location but also to a mental destination. There isn't anything exciting, fun, magical, or unique about being picked up by a city bus at AKL and being taken to MK, even if they call it a "motor coach."
If TWDC is so dead set on sticking with buses at WDW, at the very least make a small attempt to create something even slightly interesting, like the buses at Tokyo Disneyland. I'm not saying larger versions of those are the answer (I'd prefer something a little less Mickey), but at least use some creativity. I'd love to see monorails, peoplemovers, and/or other trains moving guests across property, but I know that will never happen so at least throw us a bone and make the buses cool. Sometimes I forget that this is actually the same company that built EPCOT Center and were pioneers in almost every aspect of all things entertainment.
