This might not be exactly what you're asking, but we took some great advice a couple of weeks ago and utilized taxi's to get around a little more quickly and when I wasn't feeling up to waiting for the bus or when we needed to get to another resort for a PS.
Ask the front desk or the valet/luggage stand to call a taxi cab for you. Yellow is what they'll send. Don't use anything other than what Disney calls for you, you never know what you'll get***. We probably spent about $100 all told for our multiple trips, but it was well worth it. We did Illuminations our first night there and timing was tight with airline arrivals but it was so nice to have that taxi pick us up at the hotel. We had a large group and utilized the larger taxi van which are the same price.
Taxi's are a really great alternative to even the best WDW transportation. Hope this helps you even a little bit.

***One evening late while I was getting some change at the front desk a woman ran in screaming to help her stop the taxi that had just dropped her off - she had left something of value in the cab. The front desk had trouble helping her because she had not used a Yellow Cab (although she had Fulton's Crab House at DD call one for her and it was not a Yellow.) The front desk was at a loss as what to do since it wasn't a Yellow, she didn't remember what kind of cab, the color, the phone #, etc. They did a round about investigation by calling Fulton's, but they said that multiple cabs are available at DD and they didn't really remember specifically. I don't know what eventually happened, but I was glad I had stuck to the advice given to me about Yellow and asking the front desk/valet/luggage stand to call for me.
