I saw on the map that Coroando Springs in near DHS and AK. How long does it take to get to DTD and MK? We most likely won't have a car so we'll be using Disney transportation.
The buses were fantastic at CSR when we stayed. We stood once the entire week, never had to wait long or share with other resorts and we never seemed further than 10 minutes (give or take a few) to any park.
Google WDW transportation wizard. I don't know how accurate it is, but you can plug in to/from you're going and get the times. It includes boats and bus.
