When I was there the first weekend in October, we had a... well, I'm not gonna say a "similar" experience, because there was no crying adult or difficult-to-please child. (If my niece couldn't find something in either the World of Disney or the big toy store, I think I'd say, "Yeah, tough luck kiddo.") But like the OP, my friends and I (having gone to Downtown Disney for dinner at Bongos, which was just awful... good appetizers, TERRIBLE main course, hot and incredibly loud) opted NOT to take the boat back to POR (we'd taken the boat over) and instead take a bus. Nobody at the stop. Waited waited waited. Every bus in the world went by but one for POR. FINALLY, one showed up, got crowded quick, shift change as well.
Interestingly, that was the ONLY bad experience we had transportation wise, including on the morning of the 5k at Animal Kingdom where thousands and thousands of runners were effortlessly shuttled back to the resort. Same after the half-marathon at Epcot that night. THOUSANDS of runners, no waiting at all. Really well organized.
