Taking a bus to a park that is still open, then a bus to your resort is far better than transferring via Downtown Disney. If Downtown Disney was the only option to me I would pay for a cab instead. We had earlier dinner reservations at Boma twice last year. The first time it was easy to catch a bus to MK from AKL, then we caught the ferry to the Poly. That worked extremely well. The second trip it was EMH late at DHS. We caught that bus, then got on the boat to BWI, also very easy.
