The most efficient way using Disney transportation is to take the monorail to MK and catch the YC/BC bus. We stayed at BC and never had more than a 10 min. wait for the bus at MK. The ride itself was quick, too. Going to DHS and taking the boat will take much longer. The boat is really slow. If you have park hoppers or are going to EPCOT anyway, you could take the monorail and walk, but it's a pretty long walk all the way through the park.
