With bus drivers you never know - last year I had one take me from the YC to the GF - I didn't ask just wanted to know if any buses were still running to the MK since my dinner ADR ran really late and she said hop on I'll take you to the GF - she took a family to one of the values, too. It was late and most parks were closed.
Likewise a couple of years ago a bunch of people were trying to get from AKL to MK resorts for various ADRs after MK closed someone asked a bus driver if he'd take us there and he did - there must have been 4 or 5 groups of people and we'd been waiting forever for a bus to an open park to transfer to various MK resorts and he just took all of us straight to MK.
But generally the bus will be full and the driver needs to get everyone on the bus to AKL as promised. Once the driver drops that group all those people waiting at AK to get back to YC, BC and maybe Swolphin and BWI (or whichever resort the bus is going back to) deserve to get to their destination without time wasting detours to nearby resorts.
