Allow me to explain why I disagree with the above posters. Because AKL and AK are so close together, chances are, yes, you'll quickly get a bus from AK to AKL. But then, AKL and DTD are about as far apart as you can get on WDW property, so you may be at AKL waiting for quite a while to get a bus to DTD, and it will be a bit of a trek from there.
The 4 resorts that seem to be closest to DTD are POFQ, PO-R, OKW and SSR. And they all have bus and ferry service to DTD. If you take a bus to any of those 4 resorts, you're getting the longest part of your trek out of the way first, BUT you have more options to get the long part of the trek done first. As opposed to waiting for the single bus line that goes from AK to AKL, followed by the one bus line that will take you from AKL to DTD, you will have 3 or 4 bus lines to resorts close to DTD (3 options if POR and POFQ share a bus, 4 if not), then 2 or 3 options to get to DTD after that (bus or ferry, plus OKW and SSR have walkways to DTD). Your best bet may be to get a bus to SSR, but get dropped off at Congress Park, then walk over to DTD from there. I've done that walk, in the hot August sun, in less than 10 minutes. If you get dropped off anywhere else in SSR, you'll be closer to the ferry, but it will be much longer of a walk if you need to haul butt.
