A lot depends on the time of day and where you are going to/from. The main reason most people plan on using DTD as their hub for resort to resort transport is that it is open so late at night.
For example, if you are staying at Pop, and you want to go to Jiko for dinner, if you go the theme park route, you would think a bus to AK would be the thing to do, followed by a bus to AKL. But AK closes very early most of the year, so the park may not even be open when you GO to dinner, let alone when you're ready to return to your resort. But you can catch a bus from Pop to DTD, then DTD to AKL, until at least 1am.
It is better if you can plan your dining around the theme parks you intend to visit. Or, alternatively, plan them around parks that are having evening EMH, if you don't plan to go to the park. That at least means the transportation will be running later. You need to allow a minimum of 30 minutes for each connection you will be making. So if you are at a park and going to a resort, allow at least 30 minutes. If you are at your resort and planning to route through a park or DTD, allow a minimum of 60 minutes (30 to DTD, 30 from DTD).
