Through the years I have stayed @ CBR, POFQ, Poly, YC, GF and, of course, AKL/AKV. Additionally we do a lot of dinning at various resorts during our 11 and 12 day stays. We rely entirely on Disney transportation, thus I have lots of experience w/ Disney transportation @ all times of the day and night (well, not so much early morning as we west coast natives don't 'do' east coast time so well.)
I have vivid memories of lengthy waits trying to 'escape' DTD - the worst being a 2+ hour wait after Cirque de Soleil one chilly December night, another when a passenger w/ a screaming baby tried to start a fight w/ my son for 'looking at him funny', another where the bus driver pulled the bus over and went off on a rant about Disney management and how they handled driver's schedules.
But, I also remember the driver after dinner @ the YC one night who asked me where I was going when I was the only one on her MK bus @ closing and when I said the GF, she just took me directly to the GF. My favorite bus experience was closing one night @ some park waiting forever to get back to AKL, we'd been waiting so long that people in line were plotting the overthrow of Disney and hijacking the next Pop bus that sailed by and forcing it to go to AKL, once our bus finally arrived the bus driver had the near mutinous packed bus happily singing Disney songs by the end of the ride (He started off singing 'Some day my Bus will come' to the tune of 'Some day my Prince will come' from Snow White - it was hilarious w/ his modified verses and from there got us to join in on easier songs.) And surely I can't be the only one riding a bus to a park on a low crowd day when the driver has flipped on the 'this park is closed due to crowding' canned message to get a laugh from his/her riders.
My take away from all that is that no matter where I stay there will be a time or two or three where I will wait and wait while 3 MK buses come and go when I want to go to Epcot, for example. As long as I give myself lots of time to get to the inflexible time slots (ADRs) I don't get too riled about the waits. Besides, I tend to forget those hundreds of times when it was smooth and easy where I waited 5-10 minutes, got a seat and off we went.
