Good point about Epcot. Didn't dawn on me!!
We will actually have to go from WL to Cape May one morning. I'm just ferrying over to MK then bussing to BC.

Not a good idea. If you are trying to get TO a resort in the morning from a park on buses it will take a very long time to get there as you are going upstream. Buses are in a mode to get folks TO parks not to resorts in the morning.
The best way to get to early breakfasts at the Epcot resorts is to take the bus to DHS, (they start at 7am), then walk or boat to the respective resort.
By the same token, if you are staying at one of the Epcot resorts and want to go to one of the MK resorts for breakfast it is faster to take a bus to MK, then monorail to one of the MK resorts. Do not go to Studios, then try to get a bus to the MK resort.
Animal Kingdom Lodge is a bit different. There are many folks going to Boma for breakfast from other resorts, so they have regular bus service to AKL from AK early in the morning. So don't go to MK, Epcot, or Studios early in the morning thinking you can get a quick bus to AKL.
Monorail service and boat service HAS to go in a circle. Bus service does not, so that is why we recommend transferring at DHS for the Epcot resorts, and transferring at MK for the MK resorts.
The logical transfer for AKL is Animal Kingdom.
To get to any of the moderates, OKW, or Saratoga Springs for breakfast, your best bet is a taxi as there is no "easy" early transportation to those resorts.
Hope this makes sense.
