Actually, information was available to drivers several days in advance. However, most drivers chose to ignore it because they all think they know how to better run the transportation system than those who are paid to do it.
Thus if you got bad information, it wasn't a manager or Disney's fault. IT was a bus driver who failed to do his job either through ignorance or spite depending on who it was you encountered.
If there is one thing for certain at Disney, a significant portion of the Drivers hate change, don't keep theirselves up to date, and blame management for everything.
Think about how many times you have actually heard a Disney bus driver Spiel the important information about the bus trip you are taking and helpful details like bus stops, hours, and the like about your destination. This is supposed to be a requirement of the position but I bet most of you have seldom heard anything other than "THis is the Bus Stop" or "No entering through the backdoor".
While taking the monorail to the poly is one way to get to DTD, I would advise everyone to be careful about publicizing it. ONe of the major reasons the routes were changed at TTC is because of the number of Hotel Plaza and Off property guests using Disney transportation. Legitimate guests of the Magic Kingsdom resorts were having to wait through 2 or buses before they could actually get ona bus to go to DTD.
IF too many non-resort guests or guests from other Disney resorts begin to load the bus stops at the Contemporary, Poly, or Grand Floridian at peak times during the day (This is already starting to happen, especially at the POLY) , I can guarantee the guest that are actually staying in those hotels will begin to voice their complaints. If it continues to get worse in the summer, the result may be ID checks at those bus stops. First of all to make sure you are staying in a Disney resort and quite possibly that you are a registered guest of that resort in whose bus stop you are waiting.
The bus transportation is paid for by the resorts. Thus, if you stay in a Disney resort, you are paying bus fare in a sense. If you are an off property guest with a park hopper, you are only entitled to use busses that go between the parks. DownTown Disney is not a park and therefore transportation to or from parks to DTD is strictly a bonus for everyone.
