take the bus to MK then take the resort boat to MK.
Having been on the monorail the last two times...let me say...I love it more than gold. We went from POR to GF for breakfast and even tho the time was not bad at all...it was a lot of hiking just for a meal (which we would need for eating so much at bkfst!!)
we got on the bus at 8:39 and arrived at PF at the GF at 9:15.
that is not bad at all..we took the bus to EPCOT since POR is closer to Epcot, plus the Epcot bus was always way less crowded than the MK bus.
