There are easier ways to get from DTD to parks, or parks to DTD. Take a bus to the nearest resort, then head to the park or DTD. Say you are at MK and want to head to DTD. Just walk over to the CR and use their bus. And reverse it if at DTD and need to get to MK.
Want to get to Epcot from DTD? Take the bus to BW/S/D or YC/BC, and then walk over to Epcot. Same thing with DHS.
AK to DTD?? Bus to AKL and then bus to DTD.
Another fun choice, if time isn't an issue, is to bus to POR, and then take the boat to DTD..or reverse it to get to a park.
