As opposed to just taking the complimentary Disney bus from Kidani to Epcot or HS? I wouldn't think there's any good reason to complicate the trip (by taking 2 forms of transportation instead of one) and make it more expensive.
If you're concerned because you've heard that AKL is really "remote," I think those reports are exaggerated. AKL is further from some parks and closer to others, just like any other resort, but Disney bus transportation is pretty reliable and efficient 95% of the time.
