If we want to resort hop from BWV, we usually boat over to MGM, then walk over to the busses in front of the park... (The only time we don't usually do this is when MGM has closed for the night... )
My sister just did this from OKW. She had a 7:15a reservation at Chef Mickeys so I am not sure what bus she took. Her group was the only one on the bus so the driver took them over to CR. It started her vacation off just right. Later that day in MK they got dream fastpasses!! A good day!
