Not sure but don't count on it and here is why.
Disney use to provide trans from DTD to the parks but they ran into problems with people parking for free at DTD and taking the busses to the parks...it cut into the parking spaces for people using DTD and cut into their parking revenue at the TTC.
Disney provides busses for resort to parks and for parks to parks, but they exclude DTD from the parks to parks. I know when we wanted to go to DTD we had to return to the WL and then board a seperate bus for DTD.
