This month and through mid-April, new buses will be tested at WDW.
These "articulated buses" are longer and will be able to carry more Guests on the 'higher volume' routes.
I personally think Disney should expand the monorail system from resorts-to-parks and resorts-to-Downtown-Disney. Do away with most, if not all, of the buses and their stinky, pollutive, exhausts (as well as clear out a lot of traffic!).
Read this:
In July 2000, Weiss even went so far as saying, “in two years, we are committed to drastically reducing the number of buses required to fulfill our internal transportation needs.” He put the two year date on a “transport system which will whisk guests from the airport to a new hub on property in five minutes.”
In most every office room in the Magic Kingdom, there is a property map – and not all are current. Most had “Future Monorail Expansion” leaving the EPCOT pad and going through the gap between Journey Into Imagination and The Land, down by the Yacht, Beach, and Dolphin, and ending at the Studios. Some had a line leaving from there to Animal Kingdom as well.
Speculation ran rampant, and Cockerell and Weiss admitted that plans were not finalized – but they were looking at several transportation systems and knew they would not use the monorail to connect everything, just perhaps the theme parks. A lead contender was a light rail line – and though there were several rumors, I believe the most credible was a spur going from the TTC down to Fort Wilderness, Dixie Landings, and Port Orleans, and another going down Buena Vista Drive basically from Downtown Disney, Typhoon Lagoon, Carribean Beach, Studios, Coronado Springs, Blizzard Beach, and perhaps the All Stars.
C'mon, Disney-Powers-That-Be, instead of building luxury houses, build a property-wide monorail system it !!
